摘　　要：以马铃薯淀粉为原料,经苛化后,与丙烯酰胺接枝聚合,再引入叔胺基团而制备絮凝剂(PSF)。探讨了PSF对高岭土悬浊液及工厂排泄废水的絮凝作用,以及投药量、体系pH值对絮凝效果的影响。实验表明:PSF对制糖及制革厂废水具有良好的絮凝作用。Acrylamide was grafted on potato starch alkalified by NaOH, and modified potato starch reacted with tertralkylamine to obtain flocculant (psf). Focculabilities of PSF on kaoline soliquoid and wastewater from sugar/leather factory were detected. Relation of flocculabilities and quantity of flocculant used or PH value were discussed. Experiment indicated it is feasible for PSF to treat wastewater of sugar/leather factory.
