| Abstract: | A new method for the determination of trace Zn {2 } was developed.It is based on the minus catalytic effect of Zn {2 } on the oxidation of methyl red with H-2O-2 in the medium of alcohol.The best condition of determination was determined by experiment.It is simply and sensitive.It is used for the determination of Zn {2 } in water with satisfactory result. |
