THE EFFECT OF PHYSICOCHEMICAL FACTORS ON ADSORPTION PROPERTIES OF CHITOSANS IN VITRO MODEL
Journal Title: Progress on Chemistry and Application of Chitin and its Derivatives - Year 2008, Vol 0, Issue
Abstract
Biles’acids undergo adsorption by different kinds of chitosans, that confirms significant this influence on bioavailability of biles’acids in organism of person. Radiation degradation has influence on ability of bond of biles’ acids of chitosans. It does not involve incrementation of degree of degradation incrementation of amount of related biles’ acids always. It introduces in case researched to manner-differentiated chitosans. Modification effects change through degradation radiation important chitosans viscosity, which diminishes along with decrease of average weight of chitosans. Dependence has linear character from average weight important viscosity

MODIFICATION OF RELEASE RATE OF SALICYLIC ACID FROM CHITOSAN MEMBRANE
Due to continued interest in biodegradable polymers, chitosan is one of the most commonly used polymers in the field of control release of active substances. Currently as carriers of drugs, among tablets, or micro sphere...
MISCIBILITY AND INTERACTIONS IN CHITOSAN AND POLYACRYLAMIDE MIXTURES
In the present work, the results of Fourier transform infrared (FTIR) and atomic force microscopy (AFM) studies of films of chitosan acetate (ChA), polyacrylamide (PAM), and their mixtures are presented. The morphology o...
DETERMINATION OF DEGREE OF DEACETYLATION OF CHITOSAN - COMPARISION OF METHODS
Degree of deacetylation (DD) is one of the main parameters characterizing chitosan. The most precise measurements of DD require sophisticated equipment (NMR spectrometer), not available at many laboratories worldwide wor...
THE USE OF ACTIVE CARBON IMMOBILISED ON CHITOSAN BEADS FOR RB5 AND BV10 DYE REMOVAL FROM AQUEOUS SOLUTIONS
This paper presents the adsorption of dyes – the anionic Reactive Black 5 (RB5) and cationic Basic Violet 10 (BV10) dyes – on activated carbon (AC) immobilised on chitosan (CHs). The results were compared with the remova...
EVALUATION ACTIVITIES OF CHITOSAN ASCORBATE AGAINST RODS OF HELICOBACTER PYLORI ISOLATED FROM GINGIVAL POCKETS AND ATHEROSCLEROTIC PLAQUES
The aim of the study was determine activity of chitosan ascorbate against 17 strains of Helicobacter pylori. The strains were isolated from gingival pockets (7 strains), atherosclerotic plaques from carotid and femoral (...
