摘    要:采用硫酸-硝酸溶液浸提电镀污泥中的重金属,建立电感耦合等离子体原子发射光谱法(ICP-AES)测定电镀污泥浸出液中铜、锌、镍、铬、铅、镉、钡元素的分析方法。研究了仪器的工作条件及影响检测方法的干扰因素和消除。在选定的条件下,线性相关系数均为0.9999,检出限为0.002~0.01 mg/L,加标回收率为93.5%~106.0%,测定结果的相对标准偏差小于10%(n=6)。该方法准确快速,可用于电镀污泥浸出液中多种重金属的含量测定。

关 键 词:电感耦合等离子体原子发射光谱法  电镀污泥  浸出液  重金属

Abstract:Heavy metals in electroplating sludge leaching liquid such as Cu,Zn,Ni,Cr,Pb,Cd and Ba were determined by inductively coupled plasma atomic emission spectrometry with sulfuric acid-nitric acid extraction. The working conditions of the instrument and interference factors and elimination method were studied. Under the selected conditions,the linear correlation coefficients were all 0.999 9,the detection limits were between 0.002 mg/L and 0.01 mg/L,recoveries ranged from 93.5%to 106.0%,and the relative standard deviations of determination results were less than 10%(n=6). The method could quickly and accurately detect some heavy metals in electroplating sludge leaching liquid.
Keywords:ICP-AES  electroplating sludge  leaching liquid  heavy metal
