水中微量元素及重金属检测是日常环境监测的主要项目[1-2]。近年来,各类适合多元素同时测定的大型分析仪器在分析检测领域的实验室中得到了普及,使得这些实验室对多元素混合标准样品的需求日益强劲。为了更好地配合国家标准方法GB 3838-2002《地表水环境质量标准》、GB 5749-2006《生活饮用水卫生标准》和《重金属污染综合防治“十二五”规划》等有关国家标准和规划的实施,并为我国无机污
Detection of trace elements and heavy metals in water is the main project of routine environmental monitoring [1-2]. In recent years, various large-scale analytical instruments suitable for simultaneous determination of multiple elements have been popularized in laboratories in the field of analytical testing, making these laboratories increasingly strong demand for multi-element mixed standard samples. In order to better meet the national standard methods GB 3838-2002 “surface water environmental quality standards”, GB 5749-2006 “drinking water health standards” and “comprehensive prevention and control of heavy metal pollution,” “Twelfth Five-Year Plan” and other relevant national standards And the implementation of the plan, and for our inorganic pollution
