Hydrogen peroxide, feem ntau hu ua hydrogen peroxide, yog xim tsis tshua xim, yooj yim decomposed thiab tawm tshiab cov pa, thiab muaj cov nyom ntawm cov tua kab mob, deodorization thiab decolorization. Cov tshuaj muaj ntau ntawm hydrogen peroxide muaj peev xwm kho tau ntau yam kab mob, xws li 3% hydrogen peroxide yuav raug siv rau qhov mob thiab qhov ncauj, 1% Tshuaj Kho kho mob caj dab, stomatitis, gum infections thiab diphtheria. Txawm li cas los xij, qee cov kev lag luam txhaum cai siv lub tshuaj kom tsis haum thiab tshuaj ua rau cov tshuaj hydrogen peroxide ua kom pheej yig muaj cov tshuaj hydrogen peroxide (feem ntau siv hauv ntawv thiab textile kev lag luam) uas siv rau kev ua zaub mov, kom zoo dua theem hloov tau. Txawm li cas los xij, ntau dua ntawm hydrogen peroxide yuav ua rau muaj kev phom sij ntau. High concentration of hydrogen peroxide yuav pab txo tau tib neeg lub cev, ua rau kom tsis muaj kev puas tsuaj thiab cov noob caj noob ces, thiab ua rau ntau tus kab mob xws li mob plab, qhov muag, plawv thiab mob ntsws. Tam sim no, lub xeev tau txwv txoj kev siv cov tshuaj hydrogen peroxide hauv kev ua zaub mov noj. Qhov kuaj pom ntawm cov khoom no: cov kua qaub yog 0 ~ 400mg / L, thiab cov qauv coj yog 0 ~ 4000mg / kg.
Pab kev
Waterishlogged khoom noj khoom haus thiab dej haus: 1mL dej khoom los yog khoom dej soaking kua los yog kua mus kuaj raws li eluent.
Khoom noj khoom haus: noj 2G shredded kuaj hauv colorimetric raj los yog beaker, ntxiv dej ntshiab los yog dej distilled rau 20mL, siab co, soak 10min, kom ntsuas.
Nqa cov kua rau 1mL hauv lub centrifuge tube, ntxiv 4 tee ntawm qhov ntsuas pib npog tom qab co, saib qhov xim hloov.
Tshaj txiav txim
Qhov zoo qauv yog txiv kab ntxwv liab. Qhov ntau dua qhov concentration yog, ntxaum cov xim yog, tus qauv siv tau ua ib nrab quantified los ntawm cov xim phaj.
Scope ntawm daim ntawv thov
Rau qhov kev txiav txim siab sai ntawm hydrogen peroxide nyob rau hauv nqaij nyuj kab ke, hiav txwv dib, ntses, squid, cov nqaij qaib thiab cov qog.
Tsawg cov kev txwv ntawm kev paub
5mg / L.
Matters xav mloog
Cov concentration ntawm sodium hydroxide, ethanol yuav ua rau lub tsho khi ua kom pom daj, siab concentration formaldehyde, sulfite yuav ua rau lub tub raj kuaj xiav, tab sis nrog cov qauv kuaj (txiv kab ntxwv liab) yog txawv txav, tsis txhob cuam tshuam nrog kev txiav txim siab.
Txoj kev no yog txoj kev nrhiav pom zoo nyob hauv thaj chaw, thiab ntau hom kev ncaj ncees yuav tsum yog raws li lub tebchaws txoj cai.
Lub raj tshuaj centrifuge tub ntxhais yuav rov qab siv tau tom qab tu tsev.
Preservation conditions
Chav tsev kub, qhov foob, lub teeb, qhov cua thiab kev txuag qhuav, lub neej txee ntawm 1 xyoos.
