Modeling of Experimental Adsorption Isotherm Data for Chlorothalonil by Nairobi River Sediment

Authors(4) :-James K. Mbugua, Peterson M. Guto, Vincent O. Madadi, Geoffrey N. Kamau

The investigated adsorption data of chlorothalonil on Nairobi River sediment using different models. Effects of initial concentration, different shaking time and contact time were investigated. The concentration of chlorothalonil in the clear aqueous solution (Ce) was determined by reversed phase HPLC. Determinations were made using the 15cm MCH-5- N-CAP C18 column and 85% HPLC grade acetonitrile in distilled water as the mobile phase. Adsorption isotherm study indicated that the Quasi Langmuir (Scatchard plot) fitted the experimental data with heist regression values range of 99.8 to 100. Thermodynamic study calculations showed that the Gibbs free energy for chlorothalonil was -9.2687 kj/mol calculated using Freundlich and Langmuir constants. The maximum adsorption capacity of Nairobi River sediment was 33.389 mg/ml. Kinetic studies revealed that the adsorption of chlorothalonil onto Nairobi river sediment followed a pseudo-second order kinetics.
