摘要
This work was focused on the UV-Vis spectroscopic study of removal of 5 dyes from aqueous solution. The removal of the five dyes is strongly influenced by chemical structure and electrical charge. Best degree of removal was obtained for methylviolet (90.2%) and aniline red (82.8%) while the removal of the other dyes does not exceed 35% (light green - similar to 35%, indigocarmin 25.5% and tartrazine similar to 10%). The absorption profile is very similar for all dyes, the first 5h being the most important because after that the degree of removal is maintained relatively constant.
