P2.9.8 Smart Trace Metal Monitoring System Using Homemade Voltammetric Controller and Nano Electrode Array

W. Zhang, Y. Zhao, H. Wan, X. Wang, H. X. Zhao, W. Cai & P. Wang
We present a smart trace metal monitoring system using homemade voltammetric controller and nano electrode array to detect heavy metal ions as Zn2+, Pb2+ and Cu2+. The voltammetric controller is featured with smart stage including pre-estimate and optimized measurement. The smart stage can be realized by integrated novel functions such as self-calibration, multi standard solution flow control and automatic deposition time adjustment. Moreover, a mercury-free nano electrode array, consisting gold and platinum electrodes on opposite...
