Lub hauv paus tseem ceeb uas cuam tshuam rau kev ruaj ntseg ntawm cov zaub mov-qib hydrogen peroxide yog li hauv qab no:
1. ntsuas kub
Cov tshuaj hydrogen peroxide yog qhov ruaj khov ntawm qhov kub qis dua thiab kev coj dawb huv dua. Thaum hydrogen peroxide yog rhaub kom txog 153 ° C lossis siab dua, nws yuav ua kom lub siab tawg thiab tawg. Ntawm qhov kub qis dua, cov txheej txheem rhuav tshem ntawm hydrogen peroxide tau nce mus rau qhov yooj yim, qhov kev cuam tshuam yog: 2H2O2 → 2H2O {{6}} O2 ↑ .946.94kcal.
2. PH tus nqi
Lub pH ntawm qhov nruab nrab muaj qhov zoo nyob ntawm kev ruaj ntseg ntawm hydrogen peroxide. Raws li cov kab mob acidic, cov khoom ntawm hydrogen peroxide yog qhov ruaj khov heev, thiab oxidation cov tshuaj tiv thaiv qeeb; hauv cov xov xwm alkaline, hydrogen peroxide yog qhov tsis ruaj khov thiab decomposes sai sai. Yog li ntawd, nyob rau hauv ib puag ncig alkaline, los ntawm cua sov, ntau tshaj hydrogen peroxide tuaj yeem ua kom tiav.
3. Ua tsis zoo
Kev tsis nyiam yog qhov tseem ceeb cuam tshuam rau kev ruaj ntseg ntawm hydrogen peroxide. Ntau cov hlau ions xws li divalent hlau ions, divalent manganese ions, divalent tooj liab ions, trivalent chromium ions, thiab lwm yam yuav txhawb txoj kev rhuav tshem ntawm hydrogen peroxide. Txij li thaum kev lag luam-qib hydrogen peroxide muaj ntau qhov tsis txaus xws li hlau ions, hauv cov txheej txheem ntau lawm ntawm kev lag luam-qib hydrogen peroxide, ntau ntawm cov stabilizer feem ntau ntxiv rau qhov hydrogen peroxide los tiv thaiv cov catalysis ntawm impurities.
4. Neeb
Lub teeb nrog lub yoj yoj ntawm 3200--3800Å yuav ua kom nrawm ua kom tiav sai ntawm hydrogen peroxide. Txhawm rau txhawm rau txhim kho kev ruaj khov ntawm hydrogen peroxide, nws yog qhov tsim nyog los tswj plaub qhov tseem ceeb ntawm lub teeb, cua sov, hlau ntsiab lus ntsiab lus thiab PH tus nqi.
Khoom noj khoom haus qib hydrogen peroxide muaj qhov ruaj khov zoo vim nws qhov purity siab thiab ob peb impurities xws li hlau ions. Piv txwv li, cov zaub mov qib hydrogen peroxide nrog cov ntsiab lus ntawm 35.5% tuaj yeem khaws cia rau hauv qhov chaw txias thiab muaj cua kev ua haujlwm rau ib nrab xyoo, thiab nws cov ntsiab lus zoo tuaj yeem tswj tau ntawm 35.0% - 35.4%.
