Iyini i-sodium thiosulfate nokuthi ungayithenga kanjani i-sodium thiosulfate?

Iyini i-sodium thiosulfate?

I-sodium thiosulfate (i-sodium thiosulphate) iyinhlanganisela ye-inorganic I-solid iwuketshezi oluyikristalu oluqhakaza oluncibilika kahle emanzini. I-sodium thiosulfate isetshenziswa ezimayini zegolide, ukwelashwa kwamanzi, i-chemistry yokuhlaziya, ukuthuthukiswa kwefilimu yezithombe ezisekelwe esiliva kanye nokuphrinta, kanye nemithi. Ukusetshenziswa kwezokwelapha kwe-sodium thiosulfate kufaka phakathi ukwelashwa kwe-cyanide poisoning kanye ne-pityriasis. Isohlwini Lwemithi Ebalulekile Yenhlangano Yezempilo Yomhlaba.

Yiziphi izakhiwo zamakhemikhali ze-sodium thiosulfate?

1. I-sodium thiosulfate ilahlekelwa amanzi ayikristalu emoyeni owomile ngaphezu kuka-33℃ bese ibola ibe yi-sodium sulfate kanye ne-sulphur dioxide;

2. I-sodium thiosulfate izinzile kusisombululo esingathathi hlangothi nese-alkaline futhi izobola ngokushesha esixazululweni esine-asidi, ifomula yamakhemikhali:

Na ₂S ₂O ₃+2HCl====2NaCl+H ₂O+S↓+SO ₂↑

3. I-sodium thiosulfate inekhono eliqinile lokuyinkimbinkimbi, ingakha inkimbinkimbi nge-bromide yesiliva, ifomula yokusabela:

I-AgBr + 2 Na ₂S ₂O ₃ + = + NaBr + Na ₃ Ag (S ₂O ₃) ₂

Ngokwalesi sakhiwo, i-Sodium thiosulfate ingasetshenziswa ukwenza isithombe sibe nokuthungwa okwengeziwe

Kuyini ukuncibilika kwe-sodium thiosulfate?

I-sodium thiosulfate inyibilika kalula emanzini. I-sodium thiosulfate cishe ayincibiliki ku-acetonitrile, ethanol, methanol.

Isetshenziselwani i-sodium thiosulfate?

I-sodium thiosulfate isetshenziswa kakhulu embonini.

Ukusetshenziswa kwezokwelapha

I-sodium thiosulfate isetshenziswa ekwelapheni ubuthi be-cyanide.Okunye ukusetshenziswa kuhlanganisa ukwelapha izikelemu kanye ne-tinea versicolor, kanye nokwelapha imiphumela engemihle ye-hemodialysis kanye nokwelashwa ngamakhemikhali.

Ukucutshungulwa kwezithombe

I-Silver halides, izingxenye ezijwayelekile zama-emulsions ezithombe, zincibilika lapho ukwelashwa nge-aqueous thiosulfate.Lolu hlelo lokusebenza njengesilungisi sesithombe satholwa ngu-John Herschel. Isetshenziselwa kokubili ifilimu kanye nokucubungula iphepha lezithombe; i-sodium thiosulfate yaziwa njengesilungisi sezithombe, futhi ngokuvamile ibizwa ngokuthi 'hypo', kusukela egameni lamakhemikhali lokuqala, i-hyposulphite yesoda.

Ukungathathi hlangothi kwamanzi ane-chlorine

I-sodium thiosulfate isetshenziselwa ukukhipha amanzi ompompi okuhlanganisa ukwehlisa amazinga e-chlorine ukuze asetshenziswe ezindaweni ezihlala emanzini, emachibini okubhukuda, nasezindaweni zokungcebeleka kanye nangaphakathi kwezindawo zokuhlanza amanzi ukuze kuphathwe amanzi ahlanjululwe ngemuva ngaphambi kokudedelwa emifuleni. Ukusabela kokunciphisa kufana nokusabela kokunciphisa i-iodine.

Ekuhloleni i-pH yezinto ze-bleach, i-sodium thiosulfate yenza kube lula imiphumela ekhipha imibala ye-bleach futhi ivumela umuntu ukuthi ahlole i-pH yezixazululo ze-bleach ngezinkomba eziwuketshezi. Ukusabela okufanelekile kufana nokusabela kwe-iodine: i-thiosulfate yehlisa i-hypochlorite (isithako esisebenzayo ku-bleach) futhi ngokwenza kanjalo iba yi-oxidized ibe yi-sulfate. Impendulo ephelele ithi:

4 NaClO + Na2S2O3 + 2 NaOH → 4 NaCl + 2 Na2SO4 + H2O

Ngokufanayo, i-sodium thiosulfate ihlangana ne-bromine, ikhipha i-bromine yamahhala esixazululweni. Izixazululo ze-sodium thiosulfate zivame ukusetshenziswa njengesexwayiso kumalabhorethri ekhemistri lapho usebenza ne-bromine kanye nokulahlwa okuphephile kwe-bromine, i-iodine, noma ezinye i-oxidizers ezinamandla.

Thuthukisa ikhwalithi yamanzi

i-sodium thiosulfate inothile emithonjeni yekhabhoni etholakalayo, engakhuthaza ukukhula nokukhiqizwa kwamagciwane anenzuzo nolwelwe, ithuthukise ngokushesha futhi izinze izinga lamanzi echibini. Ukusetshenziswa njalo ngaphambi kokuklama kanye nokuzalanisa kungathuthukisa kakhulu izinga lokusinda futhi kukhuthaze ukukhula okunempilo kwezilwane zasemanzini.

Iyiphi indlela yokukhiqiza ye-sodium thiosulfate?

Esikalini sezimboni, i-sodium thiosulfate ikhiqizwa ikakhulukazi emikhiqizweni yemfucuza ewuketshezi ye-sodium sulfide noma ukukhiqizwa kukadayi wesulfure.

Ukwenziwa ngezinga elincane kwenziwa ngokubilisa isisombululo esinamanzi se-sodium sulfite nesibabule.

Kanjalo, i-anion S2O32− imele uhlobo oluncibilikayo emanzini lwe-elemental sulphur.

ukukhiqizwa kwe-sodium thiosulfate ngesisombululo se-soda ash nge-sulfur dioxide gas reaction, engeza i-caustic soda neutralization, i-alkali sulfide ukususa ukungcola, ukuhlunga, bese i-sulfur powder encibilikisiwe kusixazululo esishisayo se-sodium sulfite ukuze siphendule, ngokuhlunga, ngaphezu kokungcola, ukuhlunga, engeza i-caustic soda yokwelashwa kwe-alkali, i-sodium dehydration, isikrini se-sodium, imikhiqizo ye-thiosulfate, okuyi-sodium thiosulfate.

Kuyini ukusetshenziswa kwamanje kwe-sodium thiosulfate?

I-STS igunyazwe ukwelapha ezinye izimo zezokwelapha eziyivelakancane. I-Calciphylaxis yiyona evelele kakhulu. Kuyisimo esingase sibe yingozi esibangelwa ukwehluleka kwezinso, ngokuvamile okuba imbangela engaziwa. Izilonda ze-thrombotic ziyakhula, ikakhulukazi esikhumbeni. Imiphumela enethemba itholwe ngokusebenzisa i-STS5 yomjovo. Iphinde isetshenziswe ngokuqondile ezilonda zesikhumba ngemithamo ye-250 mg / ml ngokulungiswa kwezilonda phakathi nenkathi yamasonto. Ukuphumelela kwalokhu kwelashwa kukholakala ukuthi kunezici eziningi. I-STS yaziwa njenge-ejenti elwa nokubala enezakhiwo ze-vasodilatory kanye ne-antioxidant. Okunye ukusetshenziswa kwe-STS ukuvikela ubuthi be-cisplatin. I-Cisplatin ingelinye lama-ejenti asetshenziswa kakhulu ekwelapheni izimila eziqinile. Inemiphumela emibi ezimisweni zezinso, zemizwa, zesisu kanye ne-hematological. Ukudlula ngokweqile okunobuthi kuvamile. Ukuze ugweme le nkinga, i-STS iphathwe ngempumelelo nge-cisplatin.

Ukusebenza kucatshangwa ukuthi kuhlobene nokubophezela kwe-STS ku-platinum yamahhala.Ubuthi be-Cyanide kusengesinye isimo lapho i-STS inendima yokwelapha. Ubuthi be-cyanide abujwayelekile kodwa buyingozi. Kungenzeka ezimweni eziningi. Izibonelo imililo, izinhlelo zokulawula izinambuzane, kanye nokumbiwa kwegolide. Inhlanganisela ye-STS ne-hydroxycobalamin ibonakale iphumelela. I-United States inekhithi evamile ye-cyanide antidote eqala isebenzisa umthamo omncane wokuhogela we-amyl nitrite, ilandelwe yi-intravenous sodium nitrite, futhi ekugcineni i-intravenous sodium thiosulfate.

I-STS ibonise isithembiso esithile ekwelapheni ezinye izimo. Muva nje i-STS iboniswe ukuthi isebenza njenge-ejenti elwa nokuvuvukala. Isibonelo, ekuhlulekeni kwesibindi okunamandla okubangelwa amagundane nge-lipopolysaccharide (LPS) noma i-LPS/D- Galactosamine, izinga lokusinda lathuthukiswa yi-hydrogen sulfide ne-STS ^12,13 . Lokhu okungenani kungenxa yemisebenzi yazo ye-anti-oxidative. I-STS isabela ne-GSSG (i-glutathione ene-oxidized) ukukhiqiza i-glutathione encishisiwe lapho kukhona ama-hydroxyI radicals noma ama-peroxide. Ngaphezu kwalokho, i-STS inamandla okukhiqiza i-hydrogen sulfide ngokusabela nge-trans-sulfuration enzymes ^14-16..

Ingabe i-sodium thiosulfate ingakulimaza?

Udinga ukuwusebenzisa ngokusekelwe encwadini kadokotela wakho.Futhi Inemiphumela ethile engemihle. Kanye nemiphumela yayo edingekayo, umuthi ungabangela imiphumela ethile engadingeki. Nakuba kungeyona yonke le miphumela engemihle engenzeka, uma yenzeka ingase idinge usizo lwezokwelapha.

Eminye imiphumela emibi engafakiwe ohlwini ingase yenzeke kwezinye iziguli. Uma ubona noma yimiphi eminye imiphumela, buza uchwepheshe wakho wezempilo.

Siyini isimo sokugcinwa kwe-sodium thiosulfate?

I-Sodium Thiosulfate ivamise ukupakishwa ku-50kg weplastiki enezikhwama ezihlanganisiwe.I-Thiosulfate ye-sodium kufanele igcinwe endaweni yokugcina impahla epholile, eyomile, futhi ivimbele ukuchayeka kanye nobufakazi bemvula ekuhambeni.Ungagcini futhi uhlanganiswe nama-acids nama-oxidants.

Ungayithenga kuphi i-sodium thiosulfate?
