摘    要:选取5-Br-PADAP光度法和原子吸收法分析预处理后水样的保存效果,经检测发现利用HNO,-HC1溶液作为固定剂,调节pH〈1后在无色玻璃瓶中贮存的样品,常温下可保存31d,锑回收率达95%以上,同时前处理带入的干扰离子最少,能够满足验收废水监测中质量控制要求。

关 键 词:  工业废水  环境监测  样品保存

Abstract:The article focused on the method of sample preservation of industrial wastewater containing antimony. By determi- ning the antimony in industrial wastewater with 5 - Br - PADAP and AAS, it is found out that the wastewater can be preserved in transparent glass bottle for 31 days by adding HNO3- HC1 as fixative after adjusting until pH 〈 1. The recovery of antimony is above 95%, and the interference could be reduced to the least by the method. It can satisfy the quality control of wastewater monitoring.
Keywords:antinomy  industrial wastewater  environment monitoring  sample preservation
