The Application of PLS in the Simultaneous Detection of Heavy Metal Ions Based on ASV

TONG Jijun CHEN Yuquan (Biosensor National Special Lab, Zhejiang University, Hangzhou 310027 P.R.china)  
Heavy metal ions have increasing pollution on the environment and hazard to the human. Anodic stripping voltammetry(ASV) can enhance the precision and realize the simultaneous detection. Chemometric techniques can overcome the overlapping of stripping peaks and interference between ions. We constructed the model with partial least squares(PLS) and predict the concentration of samples well, the prediction error is within 15%. In addition, we also used an array of ultramicrodisk electrodes and enhanced the precision to ppb.
