The mineralization of nitrobenzene was executed using an innovative method, wherein Ag/Cu2O semiconductors stimulated by visible light irradiation were supported with persulfate anions. Batch-wise experiments performed for the evaluation effects silver metal contents impregnated, concentrations and dosages on removal efficiency. physicochemical properties fresh reacted illustrated X-ray diffrac...

Pseudomonas putida B2 is able to grow on o-nitrophenol (ONP) as the sole source of carbon and nitrogen. ONP was converted by a nitrophenol oxygenase to nitrite and catechol. Catechol was then attacked by a catechol 1,2-dioxygenase and further degraded through an ortho-cleavage pathway. ONP derivatives which were para-substituted with a methyl-, chloro-, carboxy-, formyl- or nitro-group failed t...

metformin hydrochloride (mfh) is an oral anti-diabetic drug of biguanide class. two selective spectrophotometric methods were presented for the determination of mfh in pharmaceuticals. the methods were based on the measurement of yellow-coloured charge-transfer complexes formed between mfh and two poly-nitrophenols, namely, 2,4-dinitrophenol (dnp method, at 405 nm) and picric acid (pa method; a...
