Chromium from industrial wastewater, waste, pesticides, fertilizers, etc., always causes serious environmental problems. High levels of chromium pollution can have adverse effects on environments and living organisms. In this study, titanium salt was used to react with green tea extract to form a composite material, and the material was further used to remove hexavalent chromium in solution. The removal effect of hexavalent chromium was investigated under different reaction conditions, namely temperature, time, pH, and initial chromium concentration. The results showed that the chromium removal effect was the best under the conditions of acid to neutral pH, 45℃, reaction time of 24 h, and initial chromium concentration of 80 mg/L. This study provides a feasible method to solve the problem of chromium pollution and has high application value in wastewater treatment.
