Fe-deposited titanate nanotubes (Fe-TNTs) with high photocatalytic activity and adsorptive performance were synthesized through a one-step hydrothermal method. Initial As(III) oxidation followed by As(V) adsorption by Fe-TNTs could simultaneously remove these two toxic pollutants from aqueous solutions. The apparent rate constant value for photo-oxidation of As(III) under UV irradiation by Fe-T...

Catalytic oxidations of methane over palladium-based nanoparticles, with and without oxygen coating, are investigated using ReaxFF Molecular Dynamics simulations. The simulation results show the complete dynamic process of the above catalytic reactions at the atomic level and help to reveal the underlying mechanisms both qualitatively and quantitatively. It is found that oxygen molecules are si...

A comparison of adsorption efficiency of the three Granular Activated Carbon (GAC) produced from waste Nigerian Bamboo at different level of activation in a fixed adsorption bed is reported. Bamboo carbonization was done at temperature range of 200-400c and chemically activated at 400c with chloride salt at percentage range of 0-20%. The 0, 10 and 20% level activation were selected for water tr...

In this article a novel, sensitive and selective cathodic adsorptive stripping procedure is reported for determining of lead. The method is based on adsorptive accumulation of PbN-Nitrozo-N-Phenylhydroxylamine on a hanging mercury drop electrode, followed by the reduction of adsorbed specie by voltammetric scan while followed differential pulse modulation. The optimum conditions for analysis of...

An extraction-anodic adsorptive stripping voltammetric procedure using microwave-assisted solvent extraction and a gold ultramicroelectrode was developed for determining the pesticide ametryn in soil samples. The method is based on the use of acetonitrile as extraction solvent and on controlled adsorptive accumulation of the herbicide at the potential of 0.50 V (vs. Ag/AgCl) in the presence of ...

Recent clinical and pre-clinical data demonstrate that adjuvant antimicrobial therapy is beneficial in cancer treatment. For the first time, an electrochemical method was proposed for the simultaneous determination of acyclovir (ACV) and methotrexate (MTX) at activated or electropretreated pencil graphite electrode (EPPEG). Their simultaneous determination was achieved by cyclic voltammetry (CV...

Coal combustion by-products (CCPs) contains a certain amount of unburned carbon partcles (~4% to ~30%) without utility way. For utility of unburned carbon, this study tried to make unburned carbon be adsorbent in wastewater treatment. A activation treatment with high temperature had proceed on unburned carbon sample, and effects on adsorptive capability were appeared with results such as the ad...

Adsorptive polymeric resins have been occasionally described to enhance the production of specific secondary metabolites (SMs) of interest. Methods that induce the expression of new chemical entities in fungal fermentations may lead to the discovery of new bioactive molecules and should be addressed as possible tools for the creation of new microbial chemical libraries for drug lead discovery. ...

A sensitive method for the determination of the herbicide pindone by adsorptive stripping voltammetry using a hanging mercury drop electrode at pH 4.0 was described. The cyclic voltammogram of pindone demonstrates that compound was adsorbed at the surface of mercury electrode, and the overall reduction process was under controlled diffusion. The adsorptive peak was observed at −0.3 V, and peak ...
