Estimation of Light Intensity in a Solid–Liquid Photoreaction System

Abstract

A new random-walk model was proposed to simulate light scattering in a solid–liquid photoreactor. The light intensity in the reactor could be estimated by a model in which two significant parameters represented non-isotropic scattering and light absorption by a solid particle. Comparison between the results of scattering simulation and chemical actinometric experiments confirmed the validity of the model.
