| 摘 要： | 目的]研究农药中间体-氯乙酸生产中废盐酸的回收方法。方法]首先,配制K2SO4标准溶液,测其不同浓度下的吸光度值并绘制标准曲线;然后,测定废HCl溶液中初始SO42＋的浓度;最后,采用BaCl为沉淀剂去除SO42＋,测定其处理后溶液的SO42＋浓度。结果]用BaCl作为沉淀剂可将废HCl中绝大部分的SO42＋沉淀出来,提纯后盐酸中SO42＋含量为24.8μg/ml。结论]用BaCl提纯废HCl的工艺简单、可靠,值得推广。

| Abstract: | Objective] To explore the method for recycling of waste hydrochloric acid from chloroacetic acid production.Method] Firstly,the preparation of K2SO4 standard solution was performed,and the standard curve was drawn after measuring the absorbance of different concentration solution;secondly,the initial concentration of SO42+ was determined in the waste HCl solution;Finally,the SO42+ concentration was determined after precipitating with BaCl.Result] The results showed that the vast majority of SO42+ was pre... |
