| Abstract: | The optimum process conditions for the synthesis of cationic polyacrylamide(CPAM) using photo-initiation polymerization system by acrylamide(AM) and methacrylatoethyl trimethyl ammonium chloride(DMC) were studied.The optimal polymerization conditions were found as follows:the addition of Tween was 1%,the total quality concentration of monomer was 32%,n(DMC):n (AM) = 1:5,pH = 5.5,the dosage of photo initiator was 40μL,initiation time was 0.5 h and reaction temperature was 20℃.The cationic degree of the product was 15.27%when the intrinsic viscosity was 548 mL/g.The settling velocity was 39.2 cm/min and the transmittance was up to 98.9% when CPAM was used for high ash content and fine size coal slime water.The flocculation performance of CPAM was excellent compared with polyacrylamide,anionic polyacrylamide and amphoteric polyacrylamide. |
