The biomass of date Palm seeds (DPS) can be utilized for the sorption of Mn(II) ion from the water in the batch sorption process. The kinetics of sorption have been carried out by controlling different parameters such as initial concentration, dosage, temperature, and pH. The sorption equilibrium is achieved during the first 180 minutes. The maximum removal of Mn(II) ion is ca. 100 % upon the study conditions of Ci = 1 mg L-1, T = 35 ⁰C, 80 rpm, pH = 2, and dosage = 2 g L-1. The reaction kinetic models of pseudo-first-order and pseudosecond- order have been used to describe the sorption rate and mechanism of the Mn(II) ion onto the DPS surface. The kinetic parameters, the rate constant, and sorption capacities have been calculated. The possible sorption mechanism of Mn(II) ion onto the DPS surface is proposed.
