Pesticides in the different form are toxic to the environment and removal of its form the various sources is a difficult task. The thiram undergoes photocatalytic degradation under visible light when prepared TiO₂~PVA polymer composite was used as a photocatalyst. The data represent that prepared TiO₂~PVA polymer composite is a more efficient photocatalyst than the neat TiO₂. Photocatalytic efficiency of prepared TiO₂~PVA polymer composite was measured in term of no adsorption of pollutant, higher degradation rate and act as a photocatalyst under visible light irradiation. 150 minutes are required for the complete degradation of the thiram. The end products of photocatalytic degradation of thiram are CO₂, nitrate and sulphate.
