Study on scale inhibition properties of chitosan derivatives

Abstract

The chitosan derivatives scale inhibitor CTS-AMPS was synthesized by using chitosan and 2-acrylamido-2-methylpropane sulfonic acid as raw materials and ammonium persulphate as initiator, and the structure of the product was determined by ATR-FTIR. The scale inhibition performance of CTS-AMPS for municipal water was tested. The results showed that when the concentration factor of municipal wastewater is 2.5 times and the dosage is 30 mg/L, the scale inhibition reached 76.6%. The results of SEM show that the scale inhibition performance of CTS-AMPS is mainly due to lattice distortion.
