Abstract

The simultaneous detection of the heavy metals lead (Pb2+), cadmium (Cd2+), and zinc (Zn2+) via differential pulse anodic stripping voltammetry (DPASV) on glassy carbon comparedto pencil carbon electrode. The influences of the type and pH value of the electrolyte, and comparison of deposition and undeposition potential for pre-concentration heavy metals for the response of the DPASV detection were optimized. The results clearly show that pencil carbon electrode provided reliable analysis for Pb2+, Cd2+, and Zn2+highly oxidation current by the difference oxidation potential occurs at -0.50, -0.73 and -1.05 V, respectively. The linear ranges were for 320 - 6,580 ppb Pb2+, 320 -5,590 ppb for Cd2+, and 2,000–6,200 ppb for Zn2+.
