Abstract

The extraction of cationic resin from agro-Industrial waste (cashew nut sludge) by solvent extraction method and it was appliedfor adsorption of acid red 18 dye. Various parameters are influenced for optimizing the dye removal efficiency such as initial solution pH, initial dye molecule concentration, resin dosage, contact time, and temperature. The maximum dye removal was found of pH 3, initial dye concentration 20 mg/l, resin dose 0.12 g/100 ml, contact time in 45 min, and temperature at 328 K of 85.45 %, 98.18 %, 98.24 %, 99.18%, 99.54 % respectively.The adsorption process was well fitted with pseudo second order kinetic modeland Langmuir isotherm model. Thermodynamics parameters were found the negative values of Gibb’s energy ΔG, ΔH (45.27 kJ/mol) and ΔS (19.27 J/mol K) expressed process is spontaneous and endothermic nature.
