ABSTRACT
The preparation of biologically active material is one of the most interesting trends in the chemical modification of cellulose. The possibility of obtaining biologically active cellulosic material by sorption of procaine hydrochloride and gentamicin sulphate on CMC was investigated in this paper. The sorption of therapeutics on CMC samples with different degree of substitution was carried out in water solutions of anesthetic and antibiotic, while the desorption was done in 0.95% NaCl solution. The amount of bonded and released therapeutics was determined by UV spe-ctrophotometry. It was found that degree of substitution of car-boxymethylcellulose and concentration of chemotherapeutic water solution have significant influence on the amount of bonded anesthetic and antibiotic. The maximum amount of bonded chemotherapeutic was 72.15 mg of procaine hydrochloride and 165.49 mg of gentamicin sulphate per gram CMC. In both cases the amounts of bonded chemotherape-utics correspond to the concentration of local anesthetic and antibiotic preparation that are used in therapeutic purposes.
