The clay was beneficiated and characterised. Titanium dioxide was green synthesized with Parkia Biglobossa leaf extract. The TiO2-clay composite was used to treat wastewater of concentration up to 1000 mg/L of Zn (II) and Pb (II) ions. Effects of adsorbent dose, temperature, contact time, and pH on the percentage Zn (II) and Pb (II) ions removal were evaluated. Kinetics parameter were also determined. Characterization results showed that the clay was thermally stable at temperature up to 800oC, contains functional groups that are suitable for binding up heavy metals and adsorbing other toxic pollutants, and was highly rich in alumina and silica. Results showed that up to 99.00% Zn (II) and 92.51% Pb (II) ions were removed using 20 g/L of adsorbent at 30℃. The pseudo-second order model was the best fit for the adsorption kinetics. These experimental results presented showed that synthesized local clay-titanium nanocomposites are suitable and make good adsorbents for removing heavy metals from industrial wastewater.enAdsorptionWastewaterAluminosilicateClayTitaniumArticle
