| Abstract | : | Kinetics parameters are the essential issue in the design of water treatment systems for pollutions uptake. Though numerous studies have identified the boundary conditions that exert influence on the kinetics parameters, the influence of the dynamic initial solute concentratio (C0) to the kinetics parameters generated from fitting kinetics model to experimental data has not been investigated throughly. This study revealed a change in the kinetics parameter value due to changes in the adsorption mechanism as an effect of dynamic C0. It was observed that at higher C0 the adsorbed solute at equilibrium (qe) increases and it takes longer time to reach equibrium. As a result, the kinetics rate constant (k) calculated from adsorbtion reaction medel (Lagerhren, Ho, and RBS) was decreased. In general, Ho model exhibithigher correlation coefficient value (R2)among the other model at law C0. At high C0, Ho's R2 tend to decrease while the Lagergren and RBS's R2 was increased. The amandement mechanism from external mass transport to intra-particle diffusion as a rate limiting step was evidenced by Boyd and Weber-Morris kinetics model. Further, the physicochemical properties of the adsorbent used in this work : kitin and Fe3O4 modified horse dung humic acid (HDHA-Fe3O4 and HDHA-Ch respectively) with the solute Pb(II), Methylene Blue (MB), and Ni(II) was deeply discussed in this paper. The outcomes of this work are of prime significance for effective and optimum design for pollutant uptake by adsorption equipment. |
