为提高D301树脂对镓的吸附性能，在D301树脂表面接枝丙烯腈单体并对其进行偕胺肟转化制得功能材料D301-g-PAO。探讨了制备条件对接枝率的影响，并研究了D301-g-PAO对Ga （Ⅲ）的吸附性能。结果表明，在45℃、丙烯腈用量为16 mL、过硫酸铵单体质量分数为2%、反应16 h时，接枝率达到最大为19.77%，D301-g-PAO对镓的吸附量为383.3 mg/g。

In order to improve the adsorption performance of D301 resin to gallium, acrylonitrile monomer is grafted onto the surface of D301 resin and converted by amidoxime to prepare functional material D301-g-PAO.The influence of preparation conditions on the grafting rate is discussed, and the adsorption performance of D301-g-PAO to Ga(Ⅲ) is also studied.It is shown that the grafting rate can reach the maximum value 19.77%, and the adsorption capacity of D301-g-PAO to Ga(Ⅲ) can reach 383.3 mg·g^-1 when the reaction lasts for 16 h, reaction temperature is at 45℃, the dosage of acrylonitrile is 16 mL, and the mass fraction of ammonium persulfate is 2%.
