The analysis index of the portable metal analyzer for trace heavy metals in natural water based on anodic stripping voltammetry (ASV) were performed. Simultaneous determination and monovariated analysis of trace heavy metals were investigated both subsequently. The reasons of disturbance in analysis were also discussed. The addition of Ga (II) was testified that can eliminate the formation of the Cu-Zn intermetallic compound.
