摘要
铊是一种强烈的神经毒物,进入地表水中会污染饮用水源和土壤,危害极大。为满足我国在铊排放管控方面的需求,铊水质在线监测仪得到广泛应用,其在线监测数据的准确性和可靠性得到环境保护部门的高度重视。目前,我国各部门均未出台铊水质自动监测相关的国家标准和行业标准,且国内外铊水质在线监测的技术水平整体不足。本文开展污染源铊自动监测方法的研究,选取6种不同型号的铊水质在线监测仪开展实际水样测试,以所得的定量下限、示值误差、重复性和样本比对值为主要指标,开展性能比对与讨论,以期加强对铊自动监测方法的指导性和规范性。
Thallium is a strong nerve poison,which can contaminate drinking water and soil when it enters the surface water,causing great harm.In order to meet the demand of thallium discharge control in China,thallium online monitoring instrument has been widely used,and the accuracy and reliability of its online monitoring data have been highly valued by the environmental protection department.At present,there are no national and industry standards related to automatic monitoring of thallium water quality,and the technical level of online monitoring of thallium water quality at home and abroad is insufficient.In this paper,the performance of thallium automatic monitoring method for pollution sources is studied,six types of thallium online monitoring instruments were used for conducting actual water sample tests.The performance comparison and discussion were conducted using key metrics including the obtained limit of quantification(LOQ),indication error,repeatability,and sample comparison values,aiming to enhance the guidance and standardization of automated thallium monitoring methodologies.
