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HNO3-HCl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。 |

Abstract: |
The article focused on the method of sample preservation of industrial wastewater containing antimony. By determining 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-HCl 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. |
