- Abstract
The article reports on a research on the removal of carcinogenic direct azo dyes from aqueous solutions using calixarene derivatives. This study focuses on the synthesis of calixarenes with various internal cavities to compare the ability of the sorbents in extracting azo dyes from water through solid-liquid extraction process. It was compared with the ability of unsubstituted calixarene on carboxylic acid derivative. Sorption capacity of dyes in the presence of sulfonate groups on anionic dyes was oberved.
