Abstract: β-cyclodextrin―citric acid derivatives were synthesized trough heating of mixture of citric acid, cyclodextrin and Na2HPO4 as a catalyst. The degree of substitution of the derivatives was estimated by determination of citric acid by HPLC in the samples hydrolysates. Sorption properties of β-cyclodextrin―citric acid derivatives were determined using spectrophotometric method with methyl orange as a model sorbate. Sorption properties of β-cyclodextrin―citric acid derivatives were compared to native β-cyclodextrin.
