以乙二胺、三羟甲基丙烷三丙烯酸酯和二乙醇胺或三羟甲基氨基甲烷为原料，合成了水溶性树枝状聚（胺-酯）.讨论了树枝状聚（胺-酯）用量、离心时间及溶液pH值对于Cr3+去除率的影响.实验结果表明，25℃时，当pH=9.22，以3000 r/min的转速离心13 min，用20 mL PAE（NH2）8（c=0.01 mol/L）溶液处理10 mL CrCl3（c=0.1 mol/L）溶液时，Cr3+的去除率最高，为81.72%；25℃时，当pH=8.48，以3000 r/min的转速离心10 min，用20 mL PAE（OH）16（c=0.01 mol/L）溶液处理10 mL CrCl3（c=0.1 mol/L）溶液时，Cr3+的去除率最高，为90.85%；25℃时，当pH=7.67，以3000 r/min的转速离心7 min，用20 mL PAE（OH）24（c=0.01 mol/L）溶液处理10 mL CrCl3（c=0.1 mol/L）溶液时，Cr3+的去除率最高，为95.17%.

Water-soluble dendritic poly(amine-ester) was synthesized from ethylenediamine, trimethylolpropane triacrylate and diethanolamine or 3-hydroxymethyl-methane as raw materials.The effects of the amount of den-dritic poly (amine-ester), centrifugation time and pH on the removal of Cr3+ were discussed. The experimental re-sults showed: at 25 ℃, pH=9.22, a rotational speed of 3000 r/min for centrifugation 13 min with 20 mL PAE (NH2)8 (c=0.01 mol/L) was treated 10 mL CrCl3 (c=0.1 mol/L) solution, the highest removal rate of 81.72%; at 25 ℃, pH=8.48, a rotational speed of 3000 r/min for centrifugation 10 min with 20 mL PAE(OH)16(c=0.01 mol/L) was treated 10 mL CrCl3 (c=0.1 mol/L) solution, the highest removal rate was 90.85%; at 25 ℃, when the pH=7.67, centrifuged to 3000 r/min for 7 min, with 20 mL PAE(OH)24(c=0.01 mol/L) was treated 10 mL CrCl3 (c=0.1 mol/L) solution, the highest removal rate was 95.17%.
