Figure 8(a) and 8(b) show the growth of adsorbed amount (mg/g) at equilibrium over the surface of SPC and CMT, respectively, against increase in equilibrium concentrations. To establish the influence of As(V) concentration on the adsorption process, the equilibrium data has been analysed by linear forms of the Freundlich, Langmuir and Temkin models using Equations (4)–(6), respectively, and is shown in Table 3.
