The biosorption of Cu2+ onto the tea wastes (TW) was investigated by performing the batch experiments. The removal efficiency and biosorption capacity (q(e)) of TW was investigated as a function of pH, contact time, initial Cu2+ concentration, temperature, and TW dose. The q(e) value of 7141 increased with the increase of solution temperatures. According to the R-2 value, q(exp) and q(coa), the adsorption equilibrium was well described by the Langmuir isotherm model The highest sorption of Cu2+ onto TW was observed at the initial pH value and temperature of 6.0 and 55 degrees C, respectively. Experimental results confirming that the biosorption reaction of Cu(2+)on the TW was thought to be endothermic. By the comparison of kinetic models, results demonstrated that the system was best described by the pseudo secondorder kinetic model The negative Delta G degrees value indicated that the Cu2+ sorption onto the TW is feasible.
