Study on the Influence of Calibration Curve Preparation on Cu,Pb Analysis in Surface Water by Inductively Coupled Plasma Method and Uncertainty
Detecting Cu,Pbinsurfacewaterby ICP method was experienced,two approaches of preparingstandard curve were carried out with volumetric flask+pipettor method,and colorimetric tube+pipettor gunmethod,The relative uncertainty ofthe former method is urel(Cu)=1.57％,urel(Pb)=2.70％,The relative uncertainty of the later methodis urel(Cu)=1.64％,urel(Pb)=2.09％.The result showed that Cu,Pb had good linear relationship in the concentration range of 0 mg/L～2.0 mg/L.
