The removal of F- from aqueous solution using lanthanum and cerium modified mesoporous alumina (La/MA and Ce/MA) was studied, and characteration of the adsorbents by XRD, BET, XRF, FTIR, TEM, XPS and the pHZPC measurements were carried out. The adsorption was investigated in both batch and column adsorption systems. Batch experimental results showe...

We synthesized composite microspheres from cellulose nanocrystal (CNC), polyvinyl alcohol (PVA), and sodium alginate (SA), which were modified with polyethyleneimine (PEI) to introduce a high density of active amino sites onto the surface via the Schiff base reaction. We hypothesized that these (SA/CNC/PVA)@PEI microspheres would have a high adsorp...

Natural zeolite as a low cost clay was tested for removal of crystal violet known as a noxious dye. Five characterization techniques were used for this study Optimizing and modeling of adsorption were performed at minimum time by an applicable technique named as response surface methodology (RSM). Three effective variables (pH, temperature (T) and ...

Curli are amyloid fibrils that polymerize extracellularly from curlin, a protein that is secreted by many enteric bacteria and is important for biofilm formation. Presented here is a systematic study of the effects of curli on bacteria-clay interactions. The aggregation trends of curli-producing and curli-deficient bacteria with clay minerals were ...

An amino-functionalized magnetic metal organic framework (MOF), [email protected](Cr), was employed for laccase immobilization for the first time. The immobilized laccase was synthesized by the adsorption and covalent binding method, thus exhibited high activity recovery, large immobilization capacity and good tolerance to low pH and high temperatu...

In this work, the novel imprinted zeolite (IZ) was synthesized, and its properties and performance in terms of adsorption of p-Cresol, which represent the protein-bounded uremic toxins in aqueous phase under phosphate buffer saline, were studied and compared with the synthesized zeolite-Y (ZeoY-S) and commercial CBV 100 zeolite-Y (ZeoY-C). The ZeoY...

We investigate the interaction of horse heart cytochrome c (cyt c) with hematite nanowire array electrodes by cyclic voltammetry to study the electron transfer between redox active proteins and mineral surfaces. Using this model system, we quantify electron transfer rates between cyt c and hematite under varying electric potential and pH conditions...

A series of P doped TiO2 nanotubes (P-TNTs) catalysts were prepared for photocatalytic oxidation (PCO) of NO. Compared with TiO2 nanotubes, P-TNTs catalysts exhibited excellent catalytic activity. We confirmed that P was doped into TiO2 nanotubes lattice by XRD, Raman and TEM characterization. It was found that the enhanced PCO performance of NO wa...

Historical museums and depositories contain collections with a number of lead objects or historical documents with lead seals. Lead is a metal which has good corrosion resistance under atmospheric conditions. On the other hand, lead corrodes in an activity in an environment which contains volatile organic compounds (mainly acetic acid and formic ac...

Kail sawdust charcoal was used as an adsorbent for the removal of Torque blue, red RB and yellow M4G (textile dyes) dyes from aqueous solution. Adsorption was carried out at different concentrations of dye solution, dose of adsorbent, temperature, pH and particle size. The adsorption data were best fitted by Langmuir adsorption isotherm and pseudo-...
