Abstract
Water pollution by chemicals is of great public concern. Improvements in the quality and availability of water are however possible at relatively low costs. The objective of this work was to test the efficacy and applicability of a micaceous mineral of Kenyan origin (herein referred to as Mica-K) in the removal of Cu2+ ions from water and wastewater systems. The adsorption of Cu2+ onto mica-K was found to be dependent on experimental conditions, particularly: Contact time, adsorbate concentration, pH, particle size, sorbent dose and temperature. The sorption pattern of Cu2+ ions onto mica-K followed Langmuir, Freundlich, and Dubinin-Kaganer-Radushkevich (DKR) isotherms with correlation factors and other parameters for the isotherms confirming good agreement between theoretical models and the experimental results. Positive but small enthalpy, (ΔHo) value suggests that sorption of Cu2+ is endothermic and involves moderately weak bonding between the metal ions and mica-K. The entropy (ΔSo) value is positive indicating that there are some structural changes at the solid-liquid interface and that metal ion adsorption is likely to occur spontaneously at normal and high temperatures. Negative values for the Gibbs free energy, ΔGo, shows that the adsorption process is spontaneous in nature without any induction period and that the degree of spontaneity of the reaction increases with increase in temperature. Kinetic modeling analysis of the Elovich, pseudo-first order, pseudo-second order, intra-particle diffusion, mass transfer and intra-particle diffusivity equations using the linear coefficient of determination, R2 values showed that the pseudo-second order equation was the most appropriate model for the description of Cu2+ transport with chemical sorption as its rate limiting step. X-ray photoelectron spectroscopic (XPS) analysis for Cu2+ ion-equilibrated mica-K, demonstrated that Cu2+ containing nodules existed on the surface of the mineral. Mica-K adsorbent was compared well with a commercially available elgalite ion exchange resin from Elga Company UK, when used to treat real water samples from different sources within Kenya and industrial effluents.
