Hydrogen peroxide

Hydrogen peroxide yog ib qho tsis muaj ntxhiab thiab tsis muaj kob dawb. Qhov yeeb tshuaj no yog ib qho chaw tsis ruaj khov. Nws dissolves zoo hauv dej thiab decomposes mus rau hauv lub teeb txawm nyob rau hauv chav kub kub. Hauv qhov chaw ua hauj lwm network peroxide yog muag li 3% hydrogen peroxide. Raws li ib yam tshuaj, nws yog siv los ntawm antiseptic thiab hemostatic siv.

Hydrogen peroxide, cov mis uas muaj ob hydrogen atoms thiab ob oxygen atoms, ib tug yuav txo tau thiab oxidation zog. Nws muaj peev xwm induce oxidative cov tshuaj tiv thaiv nrog nitrites, hloov lawv ua nitrates. Tsis tas li ntawd, cov kua xauv ntawm hlau iodide tawm iodine. Nws tseem tuaj yeem rhuav tshem kev sib txuas lus.

Kev npaj ntawm hydrogen peroxide nyob rau hauv industrial tej yam kev mob yog ib tug ntawm ib tug tshuaj tiv thaiv nyob rau hauv uas organic tshuaj muab kev koom tes. Piv txwv li, catalytic oxidation ntawm isopropyl haus dej cawv. Qhov zoo tshaj plaws by-product, uas sawv tawm hauv qhov no, yog acetone. Tshuaj lom neeg kev lag luam hydrogen peroxide yog tsim thiab vim li ntawm cov electrolysis ntawm sulfuric acid. Purification ntawm peroxide yog nqa tawm nrog nws cov kev coj tsis meej distillation.

Hydrogen peroxide yog dav siv nyob rau hauv kev lag luam thiab nyob rau hauv lub tsev. Piv txwv, nyob rau hauv cov kev lag luam textile nws ua cov ntaub ntawm cov ntaub, thiab hauv cov ntoo ua lawv siv nws hauv cov ntawv sau. Raws li cov txheej txheem oxidising, peroxide ua haujlwm rau roj rau cov cuaj luaj. Hydrogen peroxide kuj yog siv ntau hauv kev tshawb xyuas chemistry. Hauv kev tsim ua kev lag luam, qhov yeeb tshuaj no yog ua haujlwm ua tus neeg ua hauj lwm ntau ntau uas siv rau cov khoom siv ntxeem tau. Hauv ntau yam lag luam, peroxide tuaj yeem yog ib qho ntawm cov khoom tsim los ntawm cov khoom siv tshuaj ntxuav thiab tshuaj tua kab mob, thiab tseem ua lub luag haujlwm ntawm cov kab caws dej ntawm tus neeg sawv cev hydrogenating.

3% hydrogen peroxide, uas yog muag hauv lub khw muag tshuaj, pom zoo rau kev kho mob ntiav. Cov khoom muab tshuaj tua kabmob antiseptic. Qhov xav tau rau cov tshuaj peroxide kuj tau muab rau kev kho kom tob tob, sib zog ua rau lub cev muaj teeb meem hauv lawv lub cev huv. Kev ua tau zoo ntawm cov tshuaj peroxide yog piav qhia los ntawm nws lub peev xwm los tsim ntau cov khoom siv ntau, uas ua kom cov ntshav txhaws thiab kua paug, cais lawv ntawm cov nqaij. Tom ntej thawj coj ntawm antiseptic tshuaj tuskheej pathological growths. Kev ua cov txheej txheem no ua rau txo lub sijhawm ntawm lub qhov txhab zoo thiab ua kom tus neeg mob zoo dua.

Raws li ib qho kev npaj sab nrauv sab nraud tau pom zoo rau kev muab tshuaj tua kab mob rau hauv txhua qhov chaw ntawm qhov mob, nyob rau hauv daim ntawv ntawm ntau yam compresses, rau qhov yaug qhov ncauj, nrog ntau yam sclerosis, thiab lwm yam.

Hydrogen peroxide yog siv los txhuam cov hniav txha hniav thiab cov plaub hau daj. Txawm li cas los xij, nws yuav tsum nco ntsoov tias peroxide nyob rau hauv cov no oxidizes, yog li ntawd, rhuav cov ntaub so ntswg. Yog li, kev siv cov tshuaj peroxide (tshwj xeeb tshaj yog rau cov tshuaj ntxuav hniav dawb) yuav tsis pom zoo los ntawm cov kws kho mob tshwj xeeb.

Txoj kev lag luam ua noj siv hydrogen peroxide txoj kev daws teeb meem raws li ib txoj kev lim dej tua kab hluav taws xob. Nws khiav cov khoom ntawm cov tshuab uas muaj kev sib cuag nrog cov khoom. Cov chaw lag luam uas tsim cov khoom noj siv mis thiab muab ntim lawv nrog Tetra Pak tshuab kho nrog cov tshuaj peroxide. Yog li, nws cov tshuaj tua kab mob yog ua tiav.

Hydrogen peroxide kuj tseem siv tau rau cov laj thawj. Nws yog siv nyob rau hauv lub chaw ua khoom ntawm hluav taws xob twj.

Hauv tsev, nws tshem tawm cov pob zeb uas tshwm sim ntawm cov khoom tom qab lawv cov kev sib txuas nrog manganese. Cov nyhuv tshwm sim los ntawm kev tshwm sim oxidative.
