摘要
聚天冬氨酸(PASP)是一种新型的可生物降解的水处理化学品。通过对CaCO3、CaSO4、BaSO4、SrSO4和CaF2的阻垢实验,对PASP的阻垢效果作了评价。结果表明:以天冬氨酸为原料合成的PASP1对CaF2垢阻垢效果较好;以马来酸酐为原料合成的PASP2对CaSO4、BaSO4、SrSO4垢阻垢效果较好,可以考虑做反渗透系统的阻垢剂。
Polyaspartic acid(PASP) is a new type of water treatment agent which can be disposed biologically. Through the resist-scale experiments against CaCO3;CaSO4、BaSO4、SrSO4 and CaF2, the resist-scale ability of PASP was evaluated. The result showed: the product of PASP synthesized by aspartic showed excellent resist CaF2 scale ability and the product of PASP synthesized by maleamic acid showed excellent resist CaSO4、BaSO4、SrSO4 and CaF2 scale ability.
