【摘要】 研究了D30 1 (叔胺 )和D31 2 (伯胺 ) 2种弱碱性阴离子交换树脂对MoS2 -4 的吸附和解吸行为 .结果表明 ,D30 1树脂对MoS2 -4 有较好的吸附效果 ,但用 0 .5mol·L- 1 的NaOH溶液解吸时解吸率仅为 2 9.6 % ;D31 2树脂对MoS2 -4 的吸附效果较差 ,但用 0 .5mol·L- 1 的NaOH溶液解吸时解吸率可达 90 %以上 ;此外 ,将二者应用于基于MoS2 -4 同WO2 -4 性质差异的离子交换除钼工艺尚存在一定的问题更多还原

【Abstract】 Two kinds of alkalescent ion exchange resin behaviours of absorbing and desorbing MoS 2- 4 have been studied.The result shows that the D301 resin′s effect of absorbing MoS 2- 4 is better,but the effect of desorbing MoS 2- 4 with NaOH solution (0.5 mol·L -1 ) is not satisfying.On the contrary,althougth the D312 resin′s effect of absorbing MoS 2- 4 is not good, the effect of desorbing MoS 2- 4 with NaOH solution (0.5 mol·L -1 ) is better, and the desorption rate can be 88% or more. So it shows that D301 and D312 resin can not be used in the ion exchange process for separating tungsten and molybdenum. [更多还原
