Cassia javanica

The kinetic data for the adsorption of Hg(II) by the copolymer satisfactorily follow both the pseudo-second-order model (where linear plots of t vs t/qt) as well as intra-particle diffusion model (up to 3h after that data does not satisfy intra-particle diffusion model, indicating that adsorption in the beginning is diffusion controlled. The correlation coefficients (R ) and the rate constants for CJ-g-PAA are shown in Table 10.4. While the isotherm studies indicate unilayer 

Hg(II) mg/L Lagergren Pseudo Second Order Intra-Particle Diffusion Model  

Hg(II) loaded copolymer sample is easy to desorb with acid and has been recycled for six consecutive cycles. Based on thermodynamic studies, the adsorption is shown to be spontaneous, endothermic, and has good affinity for the metal ion. There is an increased randomness at the solid-solution interface during the fixation of the metal ion on the active site of the adsorbent
