【摘要】：以自制曼尼希堿(A)和對丙烯酰胺苯甲酸鈉(B)為單體原料,以過硫酸鉀和亞硫酸氫鈉為復合引發劑,采用水溶液自由基聚合法制得聚合物(AB);利用響應面法優化合成工藝條件,確定其最佳工藝條件為n(曼尼希堿A)∶n(對丙烯酰胺苯甲酸鈉B)為1.3∶1,聚合時間為6.5h及聚合溫度為80℃。采用Tafel極化曲線、AFM、XPS對該聚合物的緩蝕性能進行了研究,同時考察了該聚合物對油田廢水的除油效果。結果表明:在50℃,聚合物的投加量為0.9%時,A3鋼在20%的鹽酸溶液中緩蝕劑率達到98.9%,且該聚合物為抑制陽極為主的緩蝕劑;當聚合物加入量為50mg/L、溫度60℃、p H=5時,除油率達到90.3%。
