| Abstract: | A new method for preparing the solution of tin chloride is described,by which the concentration of the tin chloride solution in the colour reagent can be increased with a longer stabilization time;the dosage of the colour reagent can be decreased during the determination.It is indicated through a comparative experiment that the sensitivity,accuracy,solution stability and developing effectiveness of the method can all meet the requirements of environmental monitoring. |
