Abstract The adsorption of a new amphoteric cellulosic copolymer onto bentonite from aqueous solutions was studied at different salt concentrations and temperatures. The adsorption kinetics included a fast step and a slow step. The rate of initial rapid adsorption was reduced by the addition of NaCl. An increase in the concentration of added NaCl or increasing temperature decreased the amounts adsorbed. The influence of sodium dodecylsulfate and hexadecyl trimethylammonium chloride was also studied.
