In the present study we reported the feasibility of extra cellular biopolymer( PFC02) produced by Pseudomonas alcaligenes as an alternative biosorbent to remove Co(II) metallic ions from environmental and industrial wastewater. The effects such as pH, dosage of biosorbent, Co(II) initial concentration and sorbate-sorbent contact time and agitating speed on the adsorption capacities of PFC02 were studied...
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...
Adsorption experiments of vapor-phase elemental mercury (Hg0) were carried out by using two types of chemically modified CTS/SiO2 sorbents in a laboratory-scale fixed-bed reactor. The characterizations of the sorbents were analyzed using the methods of nitrogen (N2) adsorption/desorption, field-scanning electron microscope (FSEM), Fourier transform infra-red spectroscopy (FTIR) and X-ray diffraction...
The structure evolution of maize straw (MS) particles during pyrolysis was studied. The samples were characterized by ultimate analysis, Fourier transform infrared spectroscopy (FTIR), true density measurement and N2 isothermal adsorption/desorption method. The H/C and O/C atomic ratios decreased from 1.59 and 0.84 in the raw MS to 0.21 and 0.33 at 1173 K respectively, which implied that the char...
Nanostructured porous silicon is increasingly being used in a range of applications, including; optoelectronic devices, bio-sensors and drug delivery therapies. Porous silicon may be prepared by anodization or stain etching, with the surface porosity and chemical composition determined by the process used; this correlation has been characterized using a range of physicochemical methods. Nitrogen gas...
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...
