摘　　要：采用几种大孔弱碱性树脂处理H酸水溶液进行吸附筛选实验,筛选出吸附效果最好的ND900和D301两种大孔弱碱性树脂,并进行了pH对树脂吸附H酸性能的影响实验。结果表明,pH对两种树脂吸附处理H酸废水的性能影响较为明显,pH过高和过低都不利于吸附。It is introduced that the adsorption screening has been carried through by using some kinds of macroporous alkalescent resins for treating H-acid aqueous solution. The macroporous alkaleseent resins, ND900 and D301, have the best adsorbing effect. The effect of pH on the capacity of adsorbing H-acid is experimented. The results show that the pH of H-acid aqueous solution has obvious effect on the adsorbing capacity of these two kinds of resins. The adsorbing effect is adverse when the pH is too high or too low.
