| Abstract: | The synthesis of carboxymethyl chitosan with microwave and its scale inhibition were studied.The results from static antiscaling test showed that carboxymethyl chitosan has scale inhibition to Ca~(2+),Sr~(2+) and Ba~(2+).The recommendation for carboxymethyl chitosan application in antiscaling treatment are as followings: the dosage is 18 mg/L,10 mg/L,16 mg/L respectively when [Ca~(2+)] 480 mg/L,[Sr~(2+)] 260 mg/L,[Ba~(2+)] 840 mg/L. |
