Large scale characterization of phosphoproteins requires highly specific methods for purification of phosphopeptides because of the low abundance of phosphoproteins and substoichiometry of phosphorylation. Enrichment of phosphopeptides from complex peptide mixtures by IMAC is a popular way to perform phosphoproteome analysis. However, conventional IMAC adsorbents with iminodiacetic acid as the ...

Low cost activated carbon prepared from elephant dung was used as an eco-friendly adsorbent for the removal of the textile dye Rhodamine B from an aqueous solution. The adsorbent was characterized by Scanning Electron Microscope (SEM), X-Ray Diffraction(XRD), Thermo gravimetric(TG) and Fourier Transform Infra red (FT-IR)analysis. Batch adsorption experiments were carried out by varying the init...

The present research includes the safe disposal of lead-acid batteries slag using waste materials such as red mud and fly ash. The aim of this study is to investigate the adsorption of lead removal from lead acid-batteries slag on red mud and fly ash using 2 full factorial design. The combined effects of adsorbent amount, temperature, adsorbent type and leachate solution on the lead removal ads...

This research was aimed to study the adsorption of Alizarin Red S (ARS) dye using graphene oxide (GO) as an adsorbent compared with bare graphite powder (BGP). For optimum conditions, the effects of the initial concentration of ARS, solution pH, adsorbent dosage, and contact time were investigated in detail. The optimum conditions for this work were consisted of 350 mg/L initial concentration o...

In this study, powder activated carbon (PAC) and magnetic nanoparticles of iron (III) oxide were used for synthesis of Fe3O4-activated carbon magnetic nanoparticles (AC-Fe3O4 MNPs) as an adsorbent for the removal of aniline. The characteristics of adsorbent were evaluated by SEM, TEM, XRD and BET. Also, the impact of different parameters such as pH, contact time, adsorbent dosage, aniline initi...

BACKGROUND Nowadays, removal of heavy metals from the environment is an important problem due to their toxicity. OBJECTIVES In this study, a modified method was used to synthesize chitosan-coated magnetite nanoparticles (CCMN) to be used as a low cost and nontoxic adsorbent. CCMN was then employed to remove Hg(2+) from water solutions. MATERIALS AND METHODS To remove the highest percentage ...

Understanding the dynamics of fixed-bed adsorption columns for modeling is a demanding task due to the strong nonlinearities in the equilibrium isotherms, interference effects of competition of solutes for adsorbent sites, mass transfer resistances between fluid phase and solid phase, and fluid-dynamic dispersion phenomena. The interplay of these effects produces steep concentration fronts, whi...

Dual fluorescence confocal laser scanning microscopy has been used to visualise the binding of a fluorescently labelled polyclonal ovine antifluorescein F(ab)2 antibody to immobilised fluorescein. The fluorescent ligand was immobilised on a Streamline quartz base agarose matrix; a resin used industrially for expanded bed chromatography, using two different fluorescein initial concentrations in ...

Discharge of dye effluents into the natural streams may be toxic to the aquatic lives as well as human being. In the present studies, zeolite was synthesized from coal fly ash by alkaline hydrothermal treatment and mixed with magnetite nanoparticles in suspension to produce zeolite-iron oxide magnetic nanocomposite. It was used as adsorbent for the removal of malachite green dye from aqueous so...

The extraction of cellulose from sisal fiber was done initially using the steam explosion method. Extracted cellulose was grafted with acrylic acid in the presence of ceric ammonium nitrate redox initiator. The grafting phenomenon taking place between cellulose and the acrylic acid was proved by Fourier transform infrared spectroscopy (FTIR). The prepared graft copolymer was used as adsorbent f...
