硝酸钠-碘化钾-氯化十六烷基吡啶-水体系浮选分离汞(Ⅱ)的研究

Study on flotation separation of mercury(Ⅱ) by sodium nitrate-potassium iodide-cetylpyridine chloride-water system

研究了硝酸钠 碘化钾 氯化十六烷基吡啶 水体系浮选分离汞 (Ⅱ )的行为及其与常见离子分离的条件。控制pH 4 .0 ,在硝酸钠存在下 ,Hg(Ⅱ )可被碘化钾 氯化十六烷基吡啶 水体系浮选 ,而Zn(Ⅱ )、Ni(Ⅱ )、Co(Ⅱ )、Mn(Ⅱ )、Fe(Ⅱ)、Al(Ⅱ )等离子在该体系中不被浮选 ,从而实现了Hg(Ⅱ )

The flotation separation behaviour of mercury(Ⅱ) by sodium nitrate-potassium iodide-cetylpyridine chloride-water system and the conditions for the separation of mercury(Ⅱ) with other metal ions were studied. The results showed that in the presence of sodium nitrate at pH 4.0, Hg(Ⅱ) could be floated by potassium iodide-cetylpyridine chloride-water system, and Zn(Ⅱ), Ni(Ⅱ), Co(Ⅱ), Mn(Ⅱ), Fe(Ⅱ), Al(Ⅲ) could not be floated.
