摘要
对自制的超强吸水树脂的吸收性能进行了研究 ,分别考察了吸水树脂的粒径 ,溶液的 p H值 ,几种离子如 Na+ ,K+ ,Ca2 + ,Mg2 + 等的水溶液对吸水树脂吸收性能的影响。实验结果表明 ,在 p H为 6～ 8,树脂粒径为 10 0 mesh～ 12 0 mesh时 ,树脂的吸水性能最好 ,各种离子对吸水树脂吸收性能的影响大小顺序为 :Na+ <K+ <Mg2 + <Ca2 +。
The absorbent ability of the resin prepared was studied. The effect of the grain size, the pH of the solution, the metallic ion such as the Na +,K +,Ca 2+ ,Mg 2+ , etc, to the water absorbent ability was investigated. The results show that the water absorbent ability of the resin is best at the pH 6~8 and the grain size 100~120 order. The sequence of the effect of the ion to the water absorbent ability to the resin is Na +<K +<Mg 2+ <Ca 2+ .
