The aim of the present work is the use of low cost adsorbent such as date pits for the removal of malachite green (MG) dye from aqueous solution. The effect of parameters such as contact time, initial dye concentrations, pH, adsorbent dosage and temperature were performed for MG dye by batch adsorption studies. The optimum operating conditions of adsorption of MG were obtained as contact time 30 min, adsorbent dose of 0.1 g and pH 5. Fitting equilibrium data to Langmuir, Freundlich and Temkin isotherms showed that Freundlich model was more suitable to describe MG. The kinetic studies showed that the adsorption of MG followed pseudo-second-order model. Thermodynamic parameters for MG were calculated. The surface characteristics, pore structure, bonding behavior of the samples are characterized by nitrogen adsorption/desorption (BET), scanning electron microscope (SEM), The Energy Dispersive X-ray analysis (EDX) and Fourier transform infrared spectrometer (FTIR). A single stage batch adsorber was designed for adsorption of MG by DP based on the optimum isotherm
