Methyl blue

In this study, Fe3O4/g-C3N4 composite was fabricated via facile hydrothermal techniques. The Fe3O4/g-C3N4 product was used as catalysts for degradation of methylene blue (MB), rhodamine B (RhB) and methyl orange (MO) degradation with ultrasonic-assisted and H2O2.

In this study, nano Fe2O3 particles were synthesized by the combustion of gel from polyvinyl acohol (PVA) and tartaric acid (TA) for the degradation of methyl blue (MB) from the aqueous solution by the photocatalytic process. Factors affecting on Fe2O3 formation such as the pH of solution, temperature of gel formation, mole ratio of TA/PVA, temperature of calcination were investigated.

In this study, photocatalysis was applied to degrade methyl orange (MO ) and methylene blue (MB) pollutants using nanoparticles (i.e., Fe2O3, Mn2O3, Fe2O3 – Mn2O3). During photodecomposition, formed intermediates due to the incomplete reaction of pollutions and hydroxyl radical were investigated using the ions trap technique.

New enzymes of nicotine catabolism instrumental in the detoxification of the tobacco alkaloid by Arthrobacter nicotinovoranspAO1 have been iden-tified and characterized. Nicotine breakdown leads to the formation of nicotine blue from the hydroxylated pyridine ring and of c-N-methyl-aminobutyrate (CH3-4-aminobutyrate) from the pyrrolidine ring of the molecule.
