摘要
目的 改进废水中硫化物的分离方法。方法 在废水样中加入一定量的浓硫酸和锌粒,生成H2,利用H2和S2-结合生成H2S,以分离硫化物。结果 改进法的分离效率的相对误差在5％以内,加标回收率在93％一95％之间。结论 改进法比经典法设计简单,操作简便,可以推广使用。
Objective To improve the method for separating sulfuret from wastewater. Methods Certain amounts of and Zn were put into the wastewater to produce hydrogen (H2) and the H2 reacted with S2-to form H2S, and sulfuret was separated from the wastewater. Results The relative standard deviation of the improved method was less than 5% and the recovery rate obtained by adding standard material was 93%-103%. Conclusion The method was simple, easy and suitable for general use.
