摘要
采用微波消解法对洗涤剂进行前处理,应用ICP-MS法初筛洗涤剂中的有害重金属,确定需控制的重金属后,优化气体流量及泵速等影响因素,在0～0.5 mg/L范围内,各元素含量与响应强度呈良好的线性关系,相关系数为0.999 9,方法检出限低至0.016 6μg/L。
Using the microwave digestion technology,the detergent samples were digested.Then analyzed by ICP-MS.When the parameters of the equipment and the concentrations of the solution were varied,the optimum conditions were found.The intensity is linear with the concentration of element in the range of 0~0.5 mg/L.The correlation coefficient is 0.999 9 and the detection limit of this method is 0.016 6 μg/L.
