Adsorption of Silver Nanoparticles onto Different Surface Structures of Chitin/Chitosan and Correlations with Antimicrobial Activities

Size-controlled spherical silver nanoparticles (Ag NPs) can be simply prepared by autoclaving mixtures of glass powder containing silver with glucose. Moreover, chitins with varying degrees of deacetylation (DDAc < 30%) and chitosan powders and sheets (DDAc > 75%) with varying surface structure properties have been evaluated as Ag NP carriers. Chitin/chitosan-Ag NP composites in powder or sheet...

Adsorption of copper, cadmium and silver from aqueous solutions onto natural carbonaceous materials

Twelve carbonaceous materials were investigated for adsorption of Cd, Cu and Ag from water solutions. Before the adsorption experiments the chemical and structural characterization of all materials were made. The batch adsorption experiment was used. The kinetic of the adsorption process was very fast for the first five hours but very slow for approximately the next 65 hours. Nevertheless the m...

Adsorption Equilibrium and Kinetics of Lead Ion onto Synthetic Ferrihydrites

Batch experiments were conducted to study the adsorption behaviors of lead ion (Pb2+) onto ferrihydrites prepared using three different procedures which were characterized  by textural analysis (BET). The adsorption removal of Pb2+ by the three ferrihydrites (called FH-1, FH-2 and FH-3, respectively) were compared, and FH-3 shows fast adsorption kinetics as well as hig...

Adsorption and desorption behavior of silver ions onto valonia tannin resin

Valonia tannin (VT) was gelated through polymerization with formaldehyde to prepare an adsorbent, which was found effective to remove Ag from aqueous solution. The adsorption–desorption behaviors of valonia tannin resin (VTR) were investigated under various initial Ag concentrations, solution temperatures, pH values etc. The applicability of empirical kinetic models was also studied. The pseudo...
