SYNTHESIS OF MALEATE ACRYLIC ACID COPOLYMERS AND THEIR APPLICATION FOR WATER TREATMENT AGENT |
| |
| Abstract: | Maleate acrylic acid copolymers were prepared from glycol maleate(MEM),acrylic acid(AA)and MEM,AA,maleic anhydride(MA).The chelation of maleate acrylic acid copolymer for calcium ion in water was determined by Ca 2+ ion selective electrode analysis.The results showed that adding the copolymer into well water(2.0×10 -3 molCa 2+ /L)and drinking water(7.1×10 -4 molCa 2+ /L)at concertration of 0.2% and 0.04% respectively, Ca 2+ was cut down to 10 -5 mol/L,and the capacity of chelation was 3.85×10 -2 mol Ca 2+ /g copolymer. \ \ |
