The Simultaneous Extraction and Determination of Trace Copper and Zinc in Solvent Extraction
용매추출법에 의한 토양중의 미량 구리와 아연원소의 동시추출 및 정량에 관한 연구
Abstract
A rapid and selective co-extraction systems of copper and zinc-thiocyanate complex into various types of alkylamine for the simultaneous determination of two metal ions by atomic absorption spectrometry and ion chromatograph have been proposed. The quantitative extractions of Cu(II) and Zn(II) at 0.1 M-thiocyanate and 0.1 M-HCI were achieved with Aliquat 336-$CHCl_3$. The detection limits of Cu and Zn were 2 ppb and 0.9 ppb respectively.
