초록
중유 화력발전소에서 발생되는 중유회를 처리한 용출액(Fly Ash Leach Liquor; FALL)으로부터 V을 선택적으로 회수하기 위한기초 연구를 UV 분광법을 이용해 수행하였다. Ni, Fe등이 포함된 시료를 분광법으로 V을 정량할 때, Ni, Fe등의 금속이 V 정량에미치는 범위를 조사하였고 FALL 시료에 5.0M NH3 사용량과 pH 변화에 따른 금속의 침전율과 교반시간에 따른 금속 침전율의 최적 조건을 조사하였다. 25o C, pH 7.0 (5.0M NH3)에서 선택적인 V의 회수 시점은 교반 시간이 1분 이내일 때로 91.5%의 회수율을보였다.
Abstract
We studied a selective recovery condition of vanadium (V) from FALL (Fly Ash Leach Liquor) produced at a fossil fuel power station using heavy oil . By applying a spectroscopy to quantify the V in a sample, we identified a concentration range V interfered by on presence of metals such as Ni, Fe Also, the optimal vanadium precipitation rate according to the amount of 5.0M NH3 loaded to the sample, solution pH and stirring time. As a result of the experiment, the maximum selective recovery ratio of V was achieved to be higher than 91.5% when the stirring duration was less than 1 minute at pH 7.0, and 25o C.
