Study on Cu²⁺ Absorption Characteristics of Bentonite - Acrylic Acid Resin

Abstract:

Bentonite has better heavy metallic ion adsorption capacity than most of other minerals. But bentonite suspension is stalbe and it makes the solid-liquid separation very difficult. To solve this problem, bentonite was fixed into the resin by copolymerizing with acrylic acid. The reaction mechanism and the effect of bentonite on the properties of the resin were studied. The results show that the addition of bentonite has similar effect on the water-absorption and Cu2+ adsorption properties of the resin. When the mass ratio of bentonite to acrylic acid is below 1∶2, the addition of bentonite improve the water absorption and Cu2+ adsorption properties, and the water absorption and Cu2+ adsorption properties decline with more bentonite added.
