Desorption of Cadmium from Porous Chitosan Beads
Cadmium pollution of the environment has become a serious problem due to the increasing consumption of cadmium by industry in the past 20 years. Cadmium is introduced into the environment from the effluence of electroplating industry, and in solid and aqueous dis‐ charges from mining operations. Increased environmental awareness has resulted in the promulgation of more stringent legislation in ...
متن کاملThe controlled release of a drug from biodegradable chitosan gel beads.
Chitosan (CS) forms a gel in solutions with a pH above 12, and the gelation occurs at pH of about 9 in 10% amino acid solutions. In this paper, we investigated the enzymatic degradation and the drug release profile of this novel CS gel beads. The degradability of the CS gel beads was affected by the CS properties, e.g. the degree of deacetylation. The release of prednisolone (PS), as a model dr...
متن کاملThe Release of Gentamicin from Polymethylmethacrylate Beads
Gentamicin incorporated in beads of polymethylmethacrylate has been shown capable of being released over a period of several months in concentrations sufficiently high to control most pathogens. The therapeutic efficacy of such beads has been demonstrated in a model of osteomyelitis of the femur in the dog. Good tolerance has been shown, both in the animal model and in tissue cultures. In forty...
متن کاملImmobilization Of Catalase From Red Poppy On Chitosan Beads
Catalase enzyme from red poppy (Papaver rhoeas) plant was immobilized covalently with glutaraldehyde onto chitosan particles. The changes in the kinetic properties of the immobilized and free red poppy catalase were determined. The Km values were found to be 26 and 33 mM for free and immobilized red poppy catalase on chitosan. Furthermore, various characteristics of free and immobilized red pop...
متن کاملthe use of natural biopolymer of chitosan as biodegradable beads for local antibiotic delivery: release studies
background chitosan is a naturally occurring biopolymer which has been widely used in a variety of biomedical applications including local antibiotic delivery due to its excellent mechanical properties, biodegradability and biocompatibility. beads are spherical, porous carriers which are prepared from various materials including chitosan. objectives the current study aimed to fabricate a new co...
