用 D314离子交换树脂从沉钼后液中回收钼

摘要

Recovery of molybdenum by D314 ion‐exchange resin from mother liquor of precipitating molybdenum was researched .The results show that the D314 resin adsorption for molybdenum is good ,at the solution pH of about 4 ,the adsorption rate of molybdenum is 93 .40% .Using 0 .8 g/L ammonia solution as desorption agent ,the desorption rate of molybdenum is 94% .%研究了以 D314离子交换树脂从某沉钼后液中吸附回收钼。试验结果表明：D314树脂对钼的吸附效果较好，溶液 pH 控制在4．0左右，钼吸附率为93．40％；负载树脂用0．8 g／L 氨水溶液进行解吸，钼解吸率达94％。
