Abstract

We tried to measure the fixed quantity of $Ni^{2+}$ion among the metals which were eluted by distilled water from the Fly Ash Leach Liquor(FALL) with a spectrophotometric method. In addition, we researched absorbance values which had different contained quantity of $V^{3+}$ion in contrast with $Ni^{2+}$ion ppm to find out the influence of the $V^{3+}$ion existed in the FALL on the spectrophotometric fixed quantity of $Ni^{2+}$ion. As a result, when $V^{3+}$ ion has below 50% of amount of $Ni^{2+}$ion, the fixed quantity of $Ni^{2+}$ion among the FALL was able to be confirmed by spectrophotometry.

중유회로부터 증류수로 용출시킨 중유회 용출액에서 금속 중 $Ni^{2+}$이온의 정량을 분광광도법으로 측정하고자 하였다. 또 중유회용출액 중 다량 존재하는 $V^{3+}$이온이 $Ni^{2+}$이온의 분광광도법적 정량에 미치는 영향을 알아보기 위하여 $Ni^{2+}$이온 ppm 대비 $V^{3+}$이온의 함량을 달리한 시료의 흡광도를 조사한 결과 $V^{3+}$이온의 함량이 $Ni^{2+}$ 함량의 50% 이하인 조건에서는 시료 중 $Ni^{2+}$이온의 정량이 분광광도법으로 가능함을 확인하였다.
