| Abstract: | The method that trace manganse is determined with I_3~--starch system has been put forward in this paper.This is a very sensitive(ε=1.12×10~5L·mol~(-1)·cm~(-1))and selective method.Other elements,except Fe~(3+),almost are no interference.The results of the test of manganese in nature water are satisfaction. |
