Wastewater Treatment using Titanium dioxide modified Alumino-Silicate Clay

Abstract

The removal of heavy metals from wastewater using titanium dioxide modified alumino-silicate of Nigerian extract is reported. The clay was beneficiated and characterized. Titanium dioxide was green synthesized Parkia Biglogossa leaf extract. The TiOnday composite was used to treat wastewater of concentration Up to JJ mg/L of Zn (II) and Pb (II) ions. Effects of adsorbent dose, temperature, contact time, and pH on the percent Zn (II) and Pb (II) ions removal were evaluated. Kinetics parameters were also determined. Characterization results showed that the clay was thermally stable at temperature up to 800°C, contains functional groups that a* 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°C. 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.
