| Abstract: | It is found that the nonionic surfactant OP has a remarkable sensitization effect on the potential stripping of lead ( I ) and copper ( I ) ions. The optimum conditions are studied and a new method of stripping voltammetric determination of lead and copper in drinks is proposed, which is proved to be good in sensitivity, selectivity and accuracy, and is also simple, rapid and convenient in operation. |
