the reduction capacity of ammonia while present even at ppm level can be demonstrated by the increased encounter probability between ammonia and methylene blue dye (mb+) incorporated in nanomordenite and na-mor zeolites. the rate of reduction methylene blue dye by ammonia on the surface nanomordenite zeolite is faster than na-mordenite (na-mor) zeolite.because nanomordenite zeolite with high si...

Methylene blue, a prevalent cationic type dye, has been extensively utilized in textile industry. Lignin generates as byproduct and its utilization is required to add potential economic benefit of biorefinery process. Lignin-derived porous biochar, promising adsorbent, was propitiously prepared by chemical modification with different oxidation number manganese compounds (KMnO4, MnSO4, MnO2). Th...

1. Cysteamine is oxidized to hypotaurine by an enzyme extracted from horse kidney, with sulphur or sulphide acting as a cofactor. It has been now found that, when the enzyme is omitted, sulphur and sulphide are able to catalyse the oxidation of cysteamine to cystamine by molecular oxygen. 2. Methylene blue may be used in catalytic amounts as a cofactor in the enzymic oxidation of cysteamine to ...

In this study, Multi-walled carbon nanotube-CO-NH(CH2)2NH-SO3H was prepared through the functionalization of commercial multi-walled carbon nanotubes in three steps and then it was characterized using Fourier Transform Infrared Spectroscopy (FTIR) and Transmission Electron Microscopy (TEM). In addition, the adsorption of Methylene Blue was investigated by using these nanotubes. In order to remo...

The purpose of this research was the evaluation of low cost adsorbent of walnut bark granule for MB dye removal from aqueous environments. Materials & Methods: In this experimental research, the effect of various operating parameters...

This study was performed to investigate the electrochemical oxidation of a solution containing methylene blue dye by using a tin oxide (SnO2) electrode. The effect of several operating factors such as electrolyte types, current density, initial dye concentration, and pH were investigated by following the discolorationand COD removal. The results show th...

The ability of coconut husk to remove methylene blue from solution was investigated. Factors such as initial dye concentration, contact time, adsorbent dosage and pH of solution were studied. Results show that Langmuir isotherm can be successfully applied to the methylede blue coconut husk system and that coconut husk is a suitable adsorbent for such a dye. Maximum adsorption capacity is 99 mg ...

Premature rupture of the fetal membranes is associated with neonatal morbidity and mortality, and correct diagnosis is important. Generally diagnosis is simple, but in difficult cases obstetricians have used several techniques to differentiate between leaking liquor and urinary incontinence, including injecting dye into the amniotic cavity. The original report of this technique used Evans's blu...
