Considering industrialization and the rising amounts of wastewater, effective water treatment has become a matter of great importance. Adsorption and photocatalysis show superior results compared to conventional water purification methods. Since they are economical and environmentally friendly, many recent studies are focused on developing efficient materials for application in adsorption and photocatalysis. Zeolite is a good sorbent for many metal ions due to its specific porous structure, but it shows low adsorption capacity towards Ni2+ and Cr3+ ions. In order to improve its adsorption efficiency, zeolite and hydroxyapatite-based composite was synthesized in this study. Hydroxyapatite shows a significantly higher adsorption capacity for Ni2+ ions compared to natural zeolite. On the other hand, titanium dioxide is a widely used photocatalyst, but it suffers from high recombination rate and possess low efficiency under solar light. These limitations can easily be overcome by coupling TiO2 with a conducting polymer. Among many conducting polymers, one of the most promising is polyaniline (PANI) since it is stable, economical, and easy to synthesize. In this work, TiO2/PANI composites with different amount of PANI (0, 1, 3, 5 wt.%) were synthesized.
