中文摘要	hydrogen evolution bothers stripping analysis significantly. dioctyl phthalate-based carbon paste electrode exhibits extremely wide cathodic potential window. it is explored as a powerful substrate electrode to solve the problem of hydrogen evolution and further improve reproducibility for stripping analysis using bismuth-coated electrodes for the first time. it was successfully applied to the simultaneous determination of zn2+, cd2+, and pb2+. linear responses are obtained for zn2+ in the range of 10-100 mu g l-1 and for pb2+ and cd2+ in the range of 5-100 mu g l-1. the detection limits for zn2+, cd2+, and pb2+ are 0.1 mu g l-1, 0.22 mu g l-1 and 0.44 mu g l-1, respectively. the method has been successfully applied to the determination of zn2+,cd2+, and pb2+ in waste water samples. the detection strategy based on the combination of dioctyl phthalate-based carbon paste electrode and bismuth-coated electrodes holds great promise for stripping analysis.
