葡萄糖还原法处理化学实验废水银
Glucose Processes Chemical Experiment Wastewater by Reduction
【摘要】 银量法滴定实验中形成的沉淀AgCl在pH12的碱性介质中,与0.2 mol·L-1葡萄糖共同煮 沸40 min,可以使AgCl中的银全部还原析出,回收率为96.1％,回收银的纯度为99.0％,回收工艺简单 易行,不产生二次污染。
【Abstract】 AgCl which is formed by the titrmetric analysis can be reduced Ag. the technological process is to boil AgCl and 0.2 mol · L-1 glucose in alkali medium of pH 12 for 40 mintes. The recovery of silver is 96.1% . The purity of restored silver is 99 .0% .
