Nal-H₂SO₄-Na₂SO₃수용액系로부터 TBP를 이용한 인듐의 추출

Abstract

Nal-H₂SO₄-Na₂SO₃수용액 매질로부터 케로신에 희석한 TBP 용액을 사용하여 인듐의 추출에 관한 연구를 실시하였다. 추출의 정도와 여러 가지 금속이온들의 방해효과는 섬광계수 방법과 원자흡수분광법에 의하여 측정되었으며, 실험결과로부터 정량적인 인듐의 추출조건을 밝혀냈다.

The extraction of indium by tributylphosphate(TBP) diluted with kerosene has been studied in Nal-H₂SO₄-Na₂SO₃aqueous system for ranges of iodide, sulfuric acid and TBP concentrations. Scintillation counting and atomic absorption spectrometry have been used to determine the extents of extraction and interferences of various metal ions. The optimum condition of quantitative extraction of indium was found by this experiment.
