In the present study we reported the feasibility of extracellular biopolymer (PF-9) produced by Pseudomonas fluorescence C-9 as an alternative biosorbent to remove Pb(II) metallic ions from environmental and industrial wastewater.The ability of PF-9 to remove the metallic ions was investigated by using batch biosorption procedure. The effects such as, pH, biosorbent dosage, sorbate concentrations...
A water-soluble intermediate bi-functional compound with thioureido and carboxyl groups was prepared by reacting chitosan with ammonium thiocyanate and chloroacetic acid. The intermediate compound was then cross-linked by epichlorohydrin to prepare a novel water-insoluble cross-linked chitosan aiming to be used as an adsorbent for heavy metal wastewater treatment. Both the intermediate compound and...
The quantity and secondary structure of adsorbed albumin (Alb) and immunoglobulin G (IgG) on two kinds of biomaterial surfaces -polyurethane (PU (H50-50)) and polystyrene (PS) were studied using Fourier transform infrared spectroscopy (FTIR). The original spectra tested by FTIR were processed using second-derivation and self-deconvolution techniques to obtain the content of different secondary structures...
