Phosphotungstic acid is applied as a homogeneous catalyst for oxidative cleavage of methyl 9,10-dihydroxystearate, allowing retention the via organic solvent nanofiltration.

CdIn2S4 was prepared by ultrasonic spray pyrolysis. The prepared CdIn2S4 was characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FSEM), transmission electron microscopy (TEM), UV-visible diffuse reflectance spectroscopy (UV-Vis DRS), and N2-sorption techniques. Aqueous photocatalytic activity was evaluated by the decomposition of methyl orange under visible li...

in this study, the photocatalytic degradation of methyl orange and congo red dye was investigated inaqueous solution using c,n,s-tridoped sno2 nanoparticles as a nano photocatalyst. the degradationwas carried out under different conditions including the photocatalyst amount, initial concentrationand ph of the solution. the results indicated that the degradation of methyl orange and congo redwas...

A potential bacterial strain PMS82, capable of degrading an azo dye Acid orange as a sole source of carbon was isolated from common effluent treatment plant of Ankleshwar, India. The 16S rDNA sequence and phenotypic characteristics indicated that an isolated organism as Bacillus megaterium PMS82. This strain exhibited complete decolorization of Acid orange (100 mg/L) within 16 h, while maximall...

CeCuO3 nanoparticles with diameter 4.36 nm was synthesized by a fast and simplemicrowave method using cerric sulphate tetra hydrate and copper sulphate pentahydrate asstarting reagents. CeCuO3 was synthesized under microwave heating for 6 min without calciningsteps. The synthesized products were characterized by X-ray powder diffraction (XRD) andscanning electron microscopy (SEM) and the photoc...

The nanostructured anatase TiO2 with high thermal stability was prepared by polymeric sol-gel method without any additives. The particle size distribution of polymeric titania sol was determined by dynamic light scattering (DLS). Then properties of obtained titania were investigated by TG-DTA, XRD, FESEM and TEM. Also, the decolorization capability of resultant anatase was evaluated using methy...

Photodegradation of methyl orange was investigated using synthesized TiO2:Mg2+/zeolite as the photocatalyst. The photocatalyst was characterized by X-ray, XRF, FT-IR, and SEM. The photocatalytic activities of TiO2:Mg2+/zeolite samples were evaluated in the degradation of methyl orange under visible light irradiation. The appropriate content of Mg in the composite was obtained as 4.711 wt% with ...

Poly(ionic liquid)s nanofiber (PIL NF) membrane was derived from polyacrylonitrile by converting its cyano groups to imidazoline moieties via cyclization with ethylenediamine, followed quaternization 1-bromobutane. The novel PIL NF is further decorated photocatalyst phosphotungstic acid PW12 anion exchanging give PW-PIL. degradation rate of the supported towards methyl orange irradiated under v...

A method for rapid and accurate determination of trace quantities of SbIII was developed based on its inhibitory effect on the decolorizing reaction of methyl orange in the presence of bromate and bromide ions in acidic media. Decolorization of methyl orange by the reaction products was used to monitor the reaction spectrophotometrically at 525 nm. The method allows determination of antimony in...
