摘要：

Removal of organic pollutants from water using a low-cost approach is essential to safeguard against toxicity. Herein, the effect of silver ion doping on the photocatalytic activity of titanium dioxide (TiO2) towards the degradation of tartrazine (TA), a common food colourant and refractory water pollutant is reported. The hydrothermally synthesized nanomaterials were characterized using conventional physico-chemical techniques. The highest degradation of tartrazine (TA) (87%) was achieved within 180 min at an Ag doping concentration of 0.21% at room temperature. The study may be extended for the degradation of other similar organic pollutants in water.
