摘要: Abstract In this research, TiO2/UV photocatalytic degradation of linear alkylbenzene sulfonic acid (LAS) was examined in aqueous solution. The process performed a continuous reactor with coaxial cylinders. nanoparticles were deposited on two natural polymer bases, cotton and wool. inner cylinder the textile covered. contaminant solution passed through removal LAS more efficient than UV irradiation. Wool base illustrated significant efficiency base. system able to remove 86% pollutants approximately 100 min. could work either recycle flow or greater residence time. It concluded that there slight difference between increasing time single pass recycling flow.
