| Abstract �wcrylic Acid/Acrylamine copolymer adding single or mixed organic complexants was prepared in order to improve the behavior of the copolymer in water treatment specially in inhibiting scale and antiprecipitating. The conditions of reaction and operating process were studied. IR, solid contents and characteristic viscosities of the products were determined. The results in a simulated evaporative test indicated that the percentage of scale (as Ca����2+��) inhibition is 96��6��97��8 when 12ppm(real solid)AA/AM copolymer adding mixed organic complexants was used.���� |
