摘　　要：研究了多种离子交换树脂在强碱性条件下从拜耳法种分母液中吸附钼的性能。结果表明,1#树脂的吸附性能最好,理想条件下的工作吸附容量为10 g/L（湿树脂）以上;负载树脂用C溶液解吸,可以得到钼质量浓度8~10 g/L的解吸液,钼解吸率在72.3%以上。另外,也考察了溶液的运行方式、树脂重复使用效果等。Adsorption of molybdenum using several ion exchange resins at strong base condition from Bayer process liquor is invstigated.Experimental results indicate that 1# resin has best adsorption properties for molybdenum,and adsorption capacity is of over 10 g/L at optimal conditions.The loded resin can be desorbed by C desorbing agent.Desorbed solution can be of 8~10 g/L molybdenum concentration.Desorption ratio reaches 72.3%.In addition,the solution operation style and resin recycle are studied.
