Determination of Trace Copper, Lead and Zinc in Brines by FAAS after Co-precipitation with Calcium Carbonate

    摘要
  • 摘要: 以碳酸钙共沉淀卤水中的痕量Cu、Pb、Zn，用火焰原子吸收光谱法测定。对试剂的加入量、富集时间、酸度等影响因素进行了实验，选择了最佳的共沉淀条件。方法已用于卤水分析，加标回收率为Cu94．0％～97．6％、Pb94．0％。102％、Zn93．4％-102％。对卤水样品6次测定的相对标准偏差为Cu0．49％、Pb0．79％、Zn1．85％。

     

    Abstract: Trace copper,lead and zinc in brines were determined by flame atomic absorption spectrometry after separation and pre-concentration by co-precipitation with calcium carbonate.Some parameters influencing the co-precipitation separation,including(amounts) o
