目前非水定碳应用很广,吸收液有的用乙醇钾,有的用乙醇加乙醇胺,也有用乙醇加丙酮的,大多用氢氧化钾乙醇溶液即乙醇钾(C_2H_5OK)来滴定。能否用较简捷的方法回收使用过的吸收液已引起化验工作者的重视。我厂一年多来一直用生石灰(CaO)来处理 At present, the application of non-hydrotalcite is very broad, the absorption of some with potassium ethoxide, some with ethanol plus ethanolamine, but also useful for ethanol and acetone, mostly with potassium hydroxide ethanol solution that is potassium ethoxide (C_2H_5OK) to titration. Can use a relatively simple method to recover the used absorbent has drawn the attention of laboratory workers. I plant more than a year with lime (CaO) to deal with
