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.
