Copper ferrite activated carbon nanocomposites (CFACNC) has been used as adsorbent for the removal of mordant black 11 dye from aqueous solution and real tannery effluents. The nanocomposites was characterized using Fourier Transform infrared (FTIR), Brunauer–Emmet–Teller (BET), Scanning electron microscope (SEM) and Transmission electron microscope (TEM). Batch adsorption experiments were investigated and the effects of various parameters were studied and their optimum conditions were then applied on the selected real tannery effluents. The study showed that the maximum adsorption capacities for dye onto CFACNC at pH 4 were found to be 0.73 and 4.13 mg/g for tannery A and B respectively. Langmuir isotherm described the adsorption of dye onto CFACNC while kinetic studies followed pseudo second-order.Keywords: Adsorption, tannery, effluents , dye
