摘要：
The aim of the present work was to characterize the photoactive refill used in the process of photocatalytic decomposition of organic dye (Acid Red 18) in water. Titanium dioxide was immobilized on the base material as a thin layer from the alcoholic suspension followed by thermal stabilization. The prepared coating exhibited high stability in repeated cycles of water treatment. The photoactive refill was characterized not only by the activity tests but also by XRD, FTIR and UV/Vis - DRS. The amount of titanium dioxide immobilized on a glass fabric support was determined as well. The reactor with photoactive refill solves the problem of the replacement of the reactor or its parts when the photocatalyst activity decreases.
