摘要
研究了硝酸钠 碘化钾 氯化十六烷基吡啶体系浮选分离铅 (Ⅱ )的行为及其与常见离子分离的条件。结果表明 ,控制 pH 5 .0 ,在 1.0 gNaNO3存在下 ,当 0 .1mol·L- 1碘化钾和 0 .0 1mol·L- 1氯化十六烷基吡啶溶液的用量均为 1.0ml时 ,铅 (Ⅱ )被定量浮选而与Fe2 + 、Co2 + 、Ni2 + 、Zn2 + 、Mn2 + 、Al3+ 等离子分离 ,对合成水样进行了定量浮选分离测定 ,结果满意。
It was found that from a solution buffered at pH 5.0, and by the addition of 1.0g of NaNO 3 and 1 0ml of both the solutions of 0.1mol·L -1 KI and 0.01mol·L -1 CPC, lead(Ⅱ) was separated successfully from Fe 2+ , Ni 2+ , Zn 2+ , Mn 2+ and Al 3+ by floatation. Under the optimum conditins, microamounts of lead in water samples were separated and determined by photometry satisfactorily.
