Chitosan

The application of chitosan as the coagulant/flocculant in a microfiltration process of natural water has been evaluated. In order to study fouling effects, variations in permeation velocity of demineralized water were measured at the beginning and at the end of each microfiltration experiment. Expe

their higher mechanical strength, hydrophilicity, and better cell compatibility, are promising biomaterials for tissue engineering applications. Fig. 7. The proliferation of GF cells on the surfaces of TCPS, CH/CS (90/10) and CH (100/0) (n ¼ 4, mean+S.D.). By using the freeze-gelation method, we suc

In this study, the electrospinning technique was applied to fabricate biocompatible membranes composed of PLLA (poly-L-lactic acid) and chitosan. With high porosity and interconnected structure, the electrospun membranes were suitable scaffolds for cell or tissue growth. In preparations, injection r

Nitrate content has increased in Morocco, especially in underground water of agrarian areas. Several processes including degradation processes and separation processes can remove nitrate from water. Two separating processes were studied to remove nitrate from brackish underground water: adsorption o

An efficiency of humic acids (HA) removal from aqueous solutions by complexation-ultrafiltration (COUF) process was investigated. The rejection of commercial HA (Aldrich) in the presence of two weakly basic, cationic water-soluble polymers poly(diallyl dimethylammonium chloride) (PDADMAC) and chitos

The efficiency of removal of copper ions from aqueous solutions was investigated by means of ultrafiltration enhanced with chitosan. The different experimental parameters such as initial concentration of metal ions, background electrolytes, pH solutions, ultrafiltration membranes of different molecu

In the present work, cell-specific peptides were immobilized on chitosan and PLA scaffolds. The amount of immobilization, determined by HPLC, was confirmed to be in the effective range. Results from cultures of human fetal skin fibroblasts, rat osteosarcoma, and periodontal fibroblasts demonstrated

We studied the elimination of fluorides from underground water by adsorption on chitosan followed by e lectrodialysis with the help of the CMX-ACS membranes, After determining the optimal conditions of the defluorudation of a synthetic water by the chitosan extract from the chitin of the pink shrimp
