| 摘 要： | 研究了磁性晶种对硫酸铁溶液、硫酸铬溶液、电镀污泥和红土镍矿酸浸液中铁铬的去除效果,并探讨了磁性晶种除铁铬的机制。结果表明,在电镀污泥和红土镍矿酸浸液中,当pH值高于2.5和温度80 ℃以上时磁性晶种能有效去除铁铬离子。当铁铬共存时,磁性晶种表面生成的含铁水合物具有更强的静电引力,促进了磁性晶种对铬离子的去除。

| Abstract: | Study was conducted on effect of removal of both iron and chromium ions from solution of ferric sulfate, solution of chromium sulfate, the leaching lixivium of electroplating sludge and laterite nickel ore by magnetic seed crystal, and the removal mechanism was discussed. It is shown that, as for the sulfuric acid leaching lixivium of electroplating sludge and laterite nickel ore, iron and chromium ions can be effectively removed by magnetic seed crystal at a temperature above 80 ℃, with pH value higher than 2.5. With the co-existence of iron and chromium irons, ferric hydrate generated on the surface of magnetic seed crystal has a stronger electrostatic attraction, which can facilitate the removal of chromium iron by magnetic seed crystal. |
