Removal of Pb(II), Cd(II), Zn(II), and Cu(II) from aqueous solutions using the adsorption process on bentonite has been investigated. In order to find out the effect of temperature on adsorption, the experiments were conducted at 20, 35, and 50degreesC. For all the metals, maximum adsorption was observed at 20degreesC. The rate of attaining equilibrium of… (More)
