Comparative adsorption of Cu(II), Zn(II), and Pb(II) ions in aqueous solution on the crosslinked chitosan with epichlorohydrin.
The crosslinked chitosans synthesized by the homogeneous reaction of chitosan in aqueous acetic acid solution with epichlorohydrin were used to investigate the adsorptions of three metals of Cu(II), Zn(II), and Pb(II) ions in an aqueous solution. The crosslinked chitosan characterized by 13CNMR, SEM, and elemental analysis, and the effects of pH and anion on the adsorption capacity were carried...
متن کاملInhibition of Glucan Synthesis by Casein Polymers Crosslinked by Glutaraldehyde.
Glutaraldehyde-crosslinked α-casein polymers with molecular masses of 1-5×10(5) were found to inhibit adhesive insoluble glucan formation catalyzed by glucan synthases from Streptococcus sobrinus B13, a cariogenic oral bacterium. Of the three subcomponents of the glucan synthases tested, primer-dependent insoluble glucan synthase was inhibited specifically by the M r~2.7×10(5) polymer at a conc...
متن کاملMechanical properties of skinned single muscle fibers crosslinked with glutaraldehyde.
It was shown earlier (Mikawa 1979; Prochniewicz 1979) that crosslinking of thin filaments in vitro by glutaraldehyde can "'freeze'" their structure either in the activated (in the presence of Ca"-ions) or depressed (in the absence of C a t ions) state. This treatment does not inhibit the ability of actin to bind to myosin heads and to activate myosin ATPase (Lehrer 1981; Prochniewicz-Nakayama a...
متن کاملFabrication of Porous Hydroxyapatite-Gelatin Scaffolds Crosslinked by Glutaraldehyde for Bone Tissue Engineering
In this study, to mimic the mineral and organic components of natural bone, hydroxyapatite[HA] and gelatin[GEL] composite scaffolds were prepared using the solvent-casting method combined with a freeze drying process. Glutaraldehyde[GA] was used as a cross linking agent and sodium bisulfite was used as an excess GA discharger. Using this technique, it is possible to produce scaffolds with mecha...
متن کاملfabrication of new ion sensitive field effect transistors (isfet) based on modification of junction-fet for analysis of hydronium, potassium and hydrazinium ions
a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...
