| 摘 要： | 在氯化钠存在下,研究了硫氰酸铵-氯化十六烷基三甲基铵液-固体系浮选分离汞的行为及汞与常见离子的分离条件。试验表明,控制溶液pH<6.0,在1.0 g氯化钠存在下,Hg2+的浮选率在99.2%以上,共存离子如Pb2+,Cd2+,Ni2+,Mn2+,Fe3+,Al3+等不被浮选,Hg2+能与这些金属离子很好的分离。此法已应用于合成水样中微量汞的浮选分离测定,结果满意。

| Abstract: | The behavior and conditions of flotation separation of mercury in the medium of ammonium thiocyanate-cetyltrimethylammonium chloride and sodium chloride were studied.The results showed that Hg~(2 ) could be separated completely from Pb~(2 ),Cd~(2 ),Ni~(2 ),Mn~(2 ),Fe~(3 ),Al~(3 ) by flotation at pH<6 and in the presence of 1.0 g sodium chloride.The method has been used for the flotation separation of Hg~(2 ) in the synthetic sample of water with satisfactory results. |
