The present study was undertaken to evaluate the feasibility of Pseudomonas alcaligenes biomass for the removal of strontium ions from aqueous solutions. Batch experiments were performed to study the adsorption of strontium on pH, Pseudomonas alcaligenes biomass adsorbent with respect to initial Sr(II) concentration, contact time and biomass dose. The experimental data were modeled by Langmuir and...
Hempflower-like Fe2O3 microspheres were synthesised by a simple method and its structure was determined by the scanning electron microscopy, X-ray diffraction patterns and Fourier transform infrared spectrum. The effect of reaction temperature and time on the formation and size of hempflower-like Fe2O3 microspheres was further investigated in detail. These results show that the formation of Fe2O3...
This paper aims at exploring the feasibility of adsorption filtration technology using reclaimed iron sludge coated sand (RISCS) as filter media for municipal wastewater reuse. The iron sludge as surplus waste solution derived from ferric-carbon micro-electrolysis process. Scanning electron microscope (SEM), Infrared spectroscopy (IR) and X-ray diffraction (XRD) analysis were used to investigate the...
Glycin functionalization of spherical cellulose was prepared and its application in the removal of chromium ions was investigated. The structural properties of the resulting composite material were characterized by Fourier transform infrared spectrum (FT-IR) and scanning electron microscope (SEM). The ability of the composite material for removing Cr3+ from aqueous solution was studied by batch experiments...
The modification of sodium trititanate whisker surface was performed by means of impregnation procedure to fabricate the modified sodium trititanate whisker, which was characterized by scanning electron microscopy(SEM) and infrared spectroscopy(IR). Its adsorptive performance for Co(II), Pb(II) in a static system was investigated by inductively coupled plasma atomic emission spectrometry(ICP-AES)...
BTEA-Bentonite by intercalation of surfactant benzyltriethylammonium (BTEA) was described. Product was characterized by XRD and IR techniques. The adsorption properties of BTEA-Bentonite for Crystal violet is investigated, and the results show that the sorption isotherms fit the Freundlich model very well. The adsorption process of Crystal violet onto BTEA-bentonite was spontaneous, endothermic physisorption...
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 Ni(II) metallic ions from environmental and industrial wastewater. The ability of PF-9 to remove the Ni(II) ions was investigated by using batch biosorption procedure. The effects such as pH, dosage of biosorbent, Ni(II) initial concentration...
The feasibility of powdered activated carbon (PAC) as an adsorbent to eliminate the perfluorooctanoic acid (PFOA) in the water for reuse has been studied. PAC exhibits a high affinity to adsorb PFOA on its surface. More than 95% of PFOA can be adsorbed onto PAC surface at the first hour. For common reuse water, the most optical PAC concentration was 0.125 g/L. As illustrated by IR spectra, PAC is...
