| Abstract: | A method for titration of trivalent antimony ion with idoine standard solution in sodium potassium tartrate was reported.The solution of starch was used as indicator,and the influence factors were discussed.The method was simple,accurate,rapid and reproducible,and the discoloration of destination was very sharp.It had been used for the determination of antimony in complexes with satisfactory results.The coefficients of variation were all less than 0.3%,and relative error was less than 0.2%. |
