Determination of mercury content in synthetic resin emulsion interior wall coating with quick mercury meters

提出了一种采用快速测汞仪测定合成树酯乳液内墙涂料中的有害物质汞含量的方法,给出了利用该方法测定汞含量的测定下限、测量重复性和回收率的实验结果。实验结果表明:该方法具有结果准确、操作简便、检出限低、分析速度快、灵敏度高、精密度好以及省时等优点。而且该方法在测样时无需进行样品的前处理,取样量少,无试剂污染,对环境污染小,能满足样品检验的要求。

A method for determining mercury content of harmful substances in synthetic resin emulsion interior wall coating with quick mercury meters is presented in this paper. The experimental results of the lower limit of mercury content testing, repeatability and recovery are given. The reseach results show that the method has advantages of accuracy, convenient operation, low detection limit, fast analysis speed, high sensitivity, good precision and time saving, etc. Furthermore, the method needs not the pretreatment of samples during the measurement of samples, and has the characters of small sample quantity of sampling, no reagent pollution, low environmental pollution, which can satisfy requirements of sample testing.
