用二次微分简易示波伏安法测定了金刚石酸洗废液中的痕量镍。
Trace nickel in waste solution from process of diamond cleaning by acid is determined by second order differential simple oscillographic voltammetry.
在此条件下酸洗水中的己二酸回收率可达100%，经过二次结晶后己二酸的纯度超过99%。
At these conditions, the reclaiming yield of adipic acid is 100%, and the purity can be more than 99% by recrystallization.
本发明将酸洗液中有价成分完全利用，无 二次污染，环保，降本，终产品纯度高。
The invention makes full use of valuable ingredient, with no secondary pollution, secondary pollution, low cost and high-purity material finished product.
