中文摘要:
      用氢氧化铁共沉淀分离卤水中的钴镍锰,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(Co Mn)=0.10 mg/L,LD(Ni)=0.27 mg/L,加标回收率为95.00%~102.0%,精密度(n=12)为1.05%。结果表明,本方法快速准确,可以准确测定卤水中钴镍锰。
英文摘要:
      Separation of iron hydroxide co-precipitation cobalt,nickel and manganese in brine,with 1+1 the capacity,dissolution precipitation inductively coupled plasma emission spectrometry.The detection limit of the cobalt and manganese was 0.10 mg/L,The detection limit of the nickel was 0.27 mg/L,the receveries differ from 95.00% to 102.0 %,the precision of the method was 1.05% RSD (n=12).The result showed that this method is fast and accurate,so it can satisfy the detection by rule and line of cobalt,nickel and manganese in brine.
