Rapid determination of germanium and tin by ion chromatography
نویسندگان
چکیده
A method was established for the simultaneous determination of germanium and tin in one run by ion chromatography. Using a selected eluent, Ge and Sn were separated on a bifunctional ion-exchange column, followed by a postcolumn chromogenic reaction and spectrophotometric detection at 520 nm. The whole procedure was completed within 5 min with high sensitivity and selectivity at the low-/zg/1 level. The results of real sample analysis were satisfactory.
