Abstract
The potential of solid olive wastes-based adsorbent (CuO−OC) with photocatalytic power was established for the removal of total phenolics and photocatalytic discolourization of high strength olive mill wastewater (OMW). Clear insight of the FTIR and Brunauer−Emmett−Teller analyses showed that oxygen-containing functional groups of CuO−OC likely participated in the adsorption of total phenols from the OMW via a π−π interaction, hydrogen bonding and electrostatic interaction. Also, the total pore volume of CuO−OC decreased from 0.068 to 0.052 cm3 g−1 after adsorption, which suggested that phenolics were trapped within the micro- and mesopores of CuO−OC. The adsorption kinetics revealed that ∼82.7–95% of the phenolic compounds were removed within the first 360 min which is relatively faster than adsorbents and methods reported elsewhere. The isotherm results showed that Redlich–Peterson equation fit the experimental data very well with least error (χ2 = 1.46–3.19) and high correlation coefficients (0.992–0.996), which suggested a mixture of hetero- and monolayer coverage of the phenolics on the CuO−OC surface. Results obtained herein are of practical interest and the reuse efficiency of CuO−OC remained ∼60% after 5 successive recycling.
