摘要: The feasibility of polyaniline coated sawdust composite (PAn/SD) prepared from the fruit gardening plant material Cordia sebestena for adsorption anionic dyes namely Direct Green 6 (direct dye) and Reactive Orange 16 (Reactive was investigated. Batch mode kinetic isotherm studies were analysed to evaluate effects contact time, initial dye concentration, pH temperature. maximum percentage removal 76.83% 79.50%. at an concentration 50 mg/L 30 0 C. Adsorption data studied using Pseudo first order second models. equilibrium analyzed by Freundlich Langmuir capacity Q0 varies 217.39 mg/g 135.13 DG6 100 123.45 RO16 while increasing temperature 30⁰C 50⁰C. Thermodynamic parameters also evaluated it found be spontaneous, endothermic physical in nature. results showed that synthesised Sebestena suitable aqueous solutions.
