The seed powder of Punica granatum L. in its natural form was evaluated for the removal of two types of basic dyes, crystal violet (CV) and methylene blue (MB), through batch experiments. A number of adsorption variables such as pH (2 − 10), initial concentration (25 −250 mg/L), time (0 − 250 min), and temperature (293 − 323 K) were observed. The studied eco-friendly waste material removed 91.1% of CV and 83.6% of MB at neutral pH. The optimum conditions for the experiment were at pH 7, 50 mg/L concentration, 0.2 g dose, 293 K, and 60 min. The maximum Langmuir monolayer adsorption capacities for CV and MB were 434.8 and 99.1 mg/g, respectively. Results exhibited that the adsorption consequences of both the dyes complied with pseudo-second-order kinetics. The critical statistical examination of results confirmed that the data interpreted by Langmuir isotherm. Desorption efficiencies were checked using acetic acid and sodium chloride. The re-adsorption capacities were 85% and 79% for CV and MB, respectively, which showed the possibility of reusing the used competent material.
