| Abstract: | The properties of scale-inhibiting of the polyaspartic acid to CaSO_4 were studied which included the effects of polyaspartic concentration,Ca~(2 ) concentration,SO_4~(2-) concentration,pH value and temperature on the properties of scale-inhiting of polyaspartic to CaSO_4.The effects of polyaspatic on crystallizing conformation of CaSO_4 were observed by using scanning electron microscope.The experiment results showed that the polyaspartic had excellent efficiency of scale-inhibiting to CaSO_4 for water treatment. |

| Keywords: | polyaspartic acid CaSO_4 property of scale-inhibiting scanning electron microscope |
