摘　　要：研究了通过大孔吸附树脂组合净化食品级过氧化氢获得符合SEMI C12标准的超纯度过氧化氢产品的方法,并确定了大孔吸附树脂组合比其中的任意一种大孔吸附树脂的吸附效果都要明显。吸附树脂组合净化过氧化氢的总有机碳质量浓度均小于5 mg/L,净化度均大于95%,而且重复使用吸附效果不会发生明显变化。The method for manufacturing the ultra purity hydrogen peroxide conform to the SEMI C12 standard, which by purifying food grade hydrogen peroxide with maeroporous adsorption resin combination was investigated, and the adsorption effect of macroporous adsorption resin combination is more obvious than any kind of them was determined. The total organic carbon concentration of ultra purity hydrogen peroxide was less than 5 mg/L, the purifying degree was more than 95%, and the effect of repeatedly using the adsorp- tion resin combination would not change.
