A method is described for the separation and determination of chromium(Ⅲ) with 2M-thiocyanate and 3% Aliquat 336-CCI₄ by flame atomic abstorption spectrometry. Beer's law obeys in the range of 14 ppm. The proposed method was applied for the analysis of chromium(Ⅲ) in seawater.
용매추출과 원자흡수분광법에 의한 망간(Ⅱ)의 분리 및 분석에 관한 연구

The extraction of Manganese form industrial wastewater and wastes are very important. A method is described for the separation and determination of Manganese(Ⅱ) with 0.4M-potassium thiocyanate and 3% Aliquat 336-CC14 by liquid-liquid extraction and flame atomic absorption spectrometry. Managanese(Ⅱ) have been stripped into HCI solution in the presence of foreign ions. Calibration curve showed that Beer's law obey in the range of 7 ppm. Determination of Manganese(Ⅱ) in seawater was performed by the proposed method.
