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 The adsorption and desorption behaviors of MoS2-4 by D30 1 (tertiary amine) and D31 2 (primary amine) were studied. The results showed that D30 1 resin had a good adsorption effect on MoS2 -4, However, the desorption rate was only 9.6% when desorbed with 0.5 mol·L-1 NaOH solution. The adsorption of MoS2-4 by D31 2 resin was poor, but desorbed with 0. 5 mol·L-1 NaOH solution The rate of up to 90% or more; In addition, the two are based on MoS2 -4 and WO2 -4 different nature of the ion exchange molybdenum removal process there are still some problems
