摘　　要：利用一步法,将单体、交联单体、致孔剂和引发剂超声混合,制备了γ-Al_(2)O_(3)修饰的聚(丙烯酰胺-co-亚甲基双丙烯酰胺)复合材料,同时对影响富集性能的制备条件进行优化,包括聚合温度、聚合时间、致孔剂的用量和γ-Al_(2)O_(3)纳米粒子的用量,并将其作为分离富集材料,与可见光分光光度计联用,通过检测合成色素-柠檬黄吸光度来表征所制备的复合材料的吸附性能,确定最佳制备工艺。By using the one-step method,the study mixed the monomer,crosslinking monomer,pore-forming agent and initiator to synthesizeγ-Al_(2)O_(3) modified polyacrylamide composites.Several important preparation conditions affecting the extraction efficiency such as polymerization temperature,polymerization time,the dosage of pore-forming agent andγ-Al_(2)O_(3) were optimized.The composites was used as the separation and enrichment material with combination of visible spectrophotometer detecting Tartrazine.And we characterized the adsorption performance of the composites with the detection of Tartrazine.
