| 摘 要： | 研究了腐殖酸分子量对弱碱性大孔树脂吸附腐殖酸的影响, 阐明了溶液中小分子芳环化合物(苯酚)及盐含量对树脂吸附腐殖酸的影响机制. 结果表明, 树脂对低分子量腐殖酸的吸附效果要优于高分子量腐殖酸; 低浓度苯酚在溶液中可以促进树脂吸附腐殖酸, 但溶液中苯酚浓度过高会对树脂吸附腐殖酸产生抑制作用; 溶液中的盐对树脂吸附腐殖酸的影响取决于溶液的pH值. |
| 关 键 词： | 弱碱性树脂 腐殖酸 吸附 |

| Abstract: | Adsorptions of humic acid(HA) and tanic acid(TA) on weakly basic resin(D-301) were investigated. The result indicates high molecular weight of humic acid can decrease resin's adsorption capacity. Furthermore,resin's adsorption capacity for humic acid is slightly higher in the presence of low concentration of phenol,but a decrease in resin's adsorption capacity for humic acid is observed in the test when concentration of phenol is high. NaCl and pH also show an influence to resin's adsorption capacity. |
| Keywords: | Weakly basic resin Humic acid Adsorption |
