Hydrogen Peroxide Hydrogen


ntuj ntawm cov kua peroxide:

Nyob rau hauv lub catalysis ntawm kev hloov cov hlau ions xws li fe ⁺, hydogen peroxide tuaj yeem tsim cov tshuaj tiv thaiv hydrotly badicals (· Oh H₂o₂ + Fe²⁺ → Fe³⁺ + Oh + Oh⁻ Hydroxyl radicals yog ib qho ntawm cov feem ntau hom oxidative uas paub tias yuav luag txhua organic molecules tsis muaj kev xaiv. Qhov kev tawm tsam no muaj qhov cuam tshuam tseem ceeb hauv ob qho tib si ib puag ncig kev kho mob (qib oliidation technology rau cov kuab paug) thiab biology (ua rau oxidative kev ntxhov siab puas tsuaj).

Yam	Kev qhia tshwj xeeb
H2O2 ntau dua los yog sib npaug	50
Tsis - tsis muaj zog tsawg dua lossis sib npaug	0.08
Cov kua qaub dawb tshaj lossis sib npaug	0.04
Ruaj khov tshaj lossis sib npaug	97
C Tsawg dua lossis sib npaug	0.035
NO3 tsawg dua los yog sib npaug	0.025

Daim ntawv thov cov kua peroxide:

1. Tshuaj dawb hauv lub pulp thiab textile kev lag luam: Qhov no yog qhov loj tshaj plaws kev siv ntawm hydrogen peroxide. Compared with traditional chlorine containing bleaching agents such as chlorine and hypochlorite, products bleached with hydrogen peroxide have higher and more stable whiteness, and do not produce toxic chlorine containing organic compounds such as dioxins. Lawv ib puag ncig phooj ywg thiab yog tus uas muaj npe hu ua "Chlorine dawb tshuaj dawb".
2. Tshuaj Synthesis: Xws li cov tshuaj ntsuab ntsuab, cov tshuaj tua kab mob horsoxo (xws li cov tshuaj tua kab mob polymide (ephhlorohydrin
3 .14 semiconductor thiab hluav taws xob kev lag luam: hydrogen peroxide yog tus tseem ceeb siv tshuaj lom neeg siv nyob rau hauv silicon wafer kom tshem tawm cov photoresist thiab etidic seem.
