Synthesis of a green water treatment agent and its synergistic performance with electrostatic field
An environmentally friendly binary copolymer agent was synthesized using the phosphorus-and nitrogen-free agents itaconic acid(IA)and sodium methacrylate sulfonate(SMAS)monomers,and the effects of the synthesis process conditions on the copolymer properties were systematically investigated.The optimal synthesis conditions were as follows:the mass ratio of raw materials(IA∶SMAS)was 2∶1,the polymerization temperature was 95℃,and the polymerization time was 6 h.In addition,the additions of initiator and chain transfer agent were 5%of the total mass of raw materials.The static scale inhibition ex-perimental studies showed that the synthesized copolymer has excellent scale inhibition and dispersion properties.The copolymer was combined with an electrostatic field for scale inhibition studies,and the re-sults showed that the presence of electrostatic field increased the scale inhibition performance of IA/SMAS copolymer by 17%,and that the electrostatic force had a synergistic effect with IA/SMAS copolymer.
