The use of standalone titanium dioxide (TiO2) photocatalytic treatment and one that is combined with coagulation process to treat natural organic matter (NOM) from two different water sources (synthetic water containing 10 ppm of humic acid and water samples sourced from Myponga reservoir) is investigated herein. In the combined process, the water samples were treated with a novel composite coa...

A new polyaniline/BiYTi2O7 polymer composite was synthesized by chemical oxidation in-situ polymerization method for the first time. The effect of polyaniline doping on structural and catalytic properties of BiYTi2O7 was reported. The structural properties of novel polyaniline/BiYTi2O7 have been characterized by X-ray diffraction, scanning electron microscopy, X-ray photoelectron spectroscopy a...

A detailed study on visible light photocatalytic degradation of methylene blue (MB) has been investigated in aqueous heterogeneous media containing hexagonal phase molybdenum oxide (h-MoO3) nanocrystals (NCs) which was identified as a new material for visible light driven photocatalysis. A simple and template-free solution based chemical precipitation method was employed to synthesize h-MoO3 NC...

New Zr(IV)- and Hf(IV)-based metal-organic framework photocatalysts, termed VNU-1 and VNU-2 (where VNU = Vietnam National University), were synthesized and their resulting structures fully characterized. By employing a highly π-conjugated linker, namely 1,4-bis(2-[4-carboxyphenyl]ethynyl)benzene, the optical absorption properties were effectively red-shifted into the visible light region. This ...

in this work application of seven synthetic polymers as adsorbents for the removal of hg(ii) from aqueous solution was studied. the equilibrium studies are systematically carried out in a batch process, covering various process parameters that include agitation time, adsorbent dosage, and ph of the aqueous solution. variations of hg(ii) concentration in solution have been studied through measur...

ammonium ions wastewater pollution has become one of the most serious environmental problems today. the treatment of ammonium ions is a special concern due to their recalcitrance and persistence in the environment. in recent years, various methods for ammonium ion removal from wastewater have been extensively studied. this paper reviews the current methods that have been used to treat ammonium ...
