摘要
采用D314树脂从钼精矿焙烧淋洗液中回收钼,探讨了D314树脂加入量、吸附温度、溶液pH值等因素对吸附过程的影响。结果表明,在pH=4时,吸附容量最佳;钼吸附为吸热过程,提高吸附温度,有利于钼的吸附;钼的动态吸附和动态解吸均采用20 m L/h流速,钼吸附率为96.63%,解吸率为98.81%。红外测试结果表明,10%的氨水溶液可以有效解吸负载树脂上的钼。
An experiment was conducted on the recovery of molybdenum from eluent after the roasting of molybdenum concentrate by D314 resin,and effects of D314 resin dosage,adsorption temperature,pH value of solution on the process of adsorption were explored. It is found that an optimal adsorption capacity can be reached with pH at 4,and the adsorption of molybdenum is an endothermic process. An increased adsorption temperature benefits the adsorption of molybdenum. Both dynamic adsorption and desorption of molybdenum with the flowing rate of 20 m L/h can result in molybdenum adsorption rate at 96. 63% and desorption rate at 98. 81%. An infrared testing indicates that the molybdenum on the load resin can be effectively desorbed by 10% ammonia solution.
