| 摘 要： | 以十八烷基三氯硅烷对超支化聚（胺-酯）进行改性，合成了改性的超支化聚（胺-酯）。改性的超支化聚（胺-酯）是一种既具有大量的端羟基且易从中水中分离出来的超支化聚（胺-酯）。将改性的超支化聚（胺-酯）用于吸附亚硝酸根离子，实验结果表明：改性的超支化聚合物对亚硝酸根离子的最大吸附量可达149．7mg／g，在酸性溶液中吸附量还将大大增加。

| Abstract: | We used trichloroctadecylsilan to modify the product. The modified polymers we get still with a lots of terminal hydroxyl groups are hydrophobic. And hence can be applied to adsorption nitrite. A study of nitrite adsorption onto modified hyperbranched poly(amine-ester). The result showed that the highest capacity of adsorption was 149.7mg/g. And there will be a higher adsorption capacity at lower pH values. |
