P. Shetty et al., COMPLEXOMETRIC TITRATION OF THALLIUM(III) USING 3-MERCAPTO-1,2-PROPANEDIOL AS DEMASKING AGENT, INDIAN JOURNAL OF CHEMICAL TECHNOLOGY, 1(2), 1994, pp. 129-130
A simple and selective EDTA methodinvolving masking and demasking tech
nique is proposed for the determination of thallium(III) using 3-merca
pto-1, 2-propanediol as releasing agent. Reproducible and accurate res
ults are obtained in the range 4-75 mg of thallium with relative error
of +/-0.3% and coefficient of variation not more than 0.46%.
