Lezi zicaciso ziqinisekisa ukuthi i-hypo anhydrous (i-sodium thiosulfate) ithobela izindinganiso ze-pharmacopeial nezezimboni, ngekhwalithi eqinisekisiwe ngokuhlolwa kokuhlaziya.
Izakhiwo zokunciphisa i-Hypo anhydrous kanye nokuhambisana namasistimu anamanzi ayenza ibe wusizo kulokhu:
Izithombe : Isebenza njengesilungisi sokususa ama-halide esiliva angadalulwanga kufilimu namaphrinti, ivimbela ukufiphala kwesithombe.
Ukwelapha Amanzi : Kwenza i-chlorine nama-chloramine angathathi hlangothi emanzini okuphuza, emanzini angcolile, namachibi okubhukuda ukuze kukhishwe okuphephile.
Ezokwelapha kanye Nezemithi : Isebenza njengekhambi lobuthi be-cyanide ngokwenza i-thiocyanate engenabuthi; isetshenziswa ekwelapheni i-calciphylaxis.
Ukumbiwa Kwezimayini Nokumbiwa : Kwenza kube lula ukutholakala kwegolide nesiliva ngokuncibilikisa izinsimbi eziyinkimbinkimbi ezinqubweni zokuleaching.
Ukudaya kanye Nokuxubha : Iguqula odayi babe amafomu e-leuco ancibilikayo ekucutshungulweni kwezindwangu; bleach uboya nephepha ngaphandle kokulimala.
I-Analytical Chemistry : Iqashwe njenge-titrant ekunqumeni kwe-iodometric nanjenge-reagent ekuhlolweni kwaselabhorethri.
Iphrofayela yayo ye-eco-friendly isekela izinqubo ezizinzile, ezinokuphikelela okuncane kwemvelo lapho ilawulwa kahle.
I-sodium thiosulfate anhydrous ngokuvamile ayinabo ubuthi futhi ayishi, kodwa ingabangela ukucasuka okuncane emehlweni, esikhumbeni, noma emgudwini wokuphefumula lapho uthintana ngqo noma uhogelwa uthuli. Izinyathelo ezibalulekile zihlanganisa:
Gqoka amagilavu okuzivikela, izibuko zokuphepha, kanye namamaski othuli ngesikhathi sokuphatha.
Sebenzisa ezindaweni ezinomoya omuhle; gwema ukumunca noma ukuhogela.
Uma uthintana namehlo: Hlanza ngokushesha ngamanzi amaningi imizuzu engu-15 bese ubonana nodokotela.
Ukuzinza Qaphela: Ibola ezimweni ezine-acidic ukuze ikhulule igesi ye-sulphur dioxide; gcina kude nama-acids nama-oxidizers aqinile.
Ukucatshangelwa Kwemvelo: Ubuthi obungaboli futhi buphansi basemanzini; lahla ngokwemithetho yendawo.
AmaSpredishithi Edatha Yezokuphepha (SDS) ayatholakala uma ecelwa ukuthotshelwa komthetho.
I-sodium thiosulfate anhydrous isetshenziswa njenge-ejenti yokulungisa ekuthuthukisweni kwezithombe, lapho incibilikisa ama-halide esiliva angaveziwe ukuze kunzinziswe izithombe futhi kuvinjwe ukuzwela kokukhanya okwengeziwe.
Yebo, ibonisa ukuncibilika okuphezulu emanzini, ukuncibilika ngaphezu kwamagremu angu-200 ilitha ngalinye ku-20 ° C, okwenza kube kulungele izixazululo ezinamanzi ekwelapheni kwamanzi namalungiselelo ezokwelapha.
Gcina endaweni eyomile, epholile (ngaphansi kuka-30°C) ezitsheni ezingangeni moya ukuze uvimbele ukumuncwa komswakamo kanye nokubhakwa. Inempilo yeshelufu yeminyaka engu-2-3 ngaphansi kwezimo ezikahle.
Ukusetshenziswa kwayo ekudleni kukhawulelwe ku-0.1% njengosizo lokucubungula, ngokuyinhloko ukukhishwa kwe-chlorination; ayihloselwe ukusetshenziswa ngokuqondile futhi kufanele ihambisane ne-FDA noma izindinganiso ezifanayo.
Iguqula ama-ion e-cyanide anobuthi abe yi-thiocyanate, ekhishwa izinso ngokuphephile, inikeze ukuqeda ubuthi obusheshayo ezimeni ezinobuthi obunzima.
Sinikeza ukuhlanzeka okungu-≥99% ngezitifiketi zokuhlaziya (COA) zeqeqebana ngalinye, ezifanele izidingo zebanga lezimboni nelezemithi.
Ukuze uthole izingcaphuno, amasampula, ukupakishwa ngokwezifiso, noma izeluleko zochwepheshe nge-HYPO(sodium thiosulfate) i-CAS 7772-98-7 anhydrous, xhumana nochwepheshe bethu. Siletha izixazululo ezithembekile emhlabeni wonke.
