Abstract
Studies on photocatalytic inactivation of spores of Bacillus anthracis have been carried out using nanosized titania materials and UVA light or sun light. Results demonstrated pseudo first order behaviour of spore inactivation kinetics. The value of kinetic rate constant increased from 0.4Â hâ1 to 1.4Â hâ1 indicating photocatalysis facilitated by addition of nanosized titania. Nanosized titania exhibited superior inactivation kinetics on par with large sized titania. The value of kinetic rate constant increased from 0.02Â hâ1 to 0.26Â hâ1 on reduction of size from 1000Â nm to 16Â nm depicting the enhanced rate of inactivation of Bacillus anthracis Sterne spores on the decrease of particle size.
