摘要
用Fe(OH)3共沉淀分离卤水中的铜铅锌,用1+1的王水溶解沉淀定容,电感耦合等离子发射光谱法测定。检出限为LD(Cu Zn)=0.041mg·L^(-1),LD(Pb)=0.11mg·L^(-1),加标回收率为95.25%~101.9%,精密度(n=12)为1.15%。结果表明:本方法快速准确,可以准确测定卤水中铜铅锌。
Separation of iron hydroxide co-precipitation copper,lead and zinc in brine, with 1 + 1 the capacity, dissolution precipitation inductively coupled plasma emission spectrometry.The detection limit of the copper and zinc were0.041mg·L-1, The detection limit of the lead were 0.11mg·L-1, the receveries differ from 95.25% to 101.9 %,the precision of the method were 1.15% RSD (n=12). The result shows that this method is fast and accurate, so it can satisfy the detection by rule and line of Copper, Lead and Zinc in brine.
