Nitrophenols are common components of industrial effluents and have been detected in urban and agricultural waste. Dinitroortho-cresol (DNOC) can easily enter the body through inhalation, ingestion or the skin. Yellow staining is typical in toxications via skin contact. The main toxic effects of DNOC derivatives are due to an increase in cellular metabolism. It acts directly on metabolism by in...

ABSTRACT Truncated cubic Cu-oxide nanocrystals with edge lengths of ca. 600 nm were prepared employing the low-cost copper (II) chloride as precursor. XRD revealed that truncated are present in both CuI and Cu0 state. XPS characterisation gives insight into amount each state as-prepared, oxidised, reduced recovered catalyst species. The catalytic activity was tested for reduction nitrophenols u...

The phenol-degrading strain Trichosporon cutaneum R57 utilizes various aromatic and aliphatic compounds as a sole carbon and energy source. The intracellular activities of phenol hydroxylase [EC 1.14.13.7] of a Trichosporon cutaneum R57 strain grown on phenol (0.5 g/l) were measured. Different toxic phenol derivatives (cresols, nitrophenols and hydroxyphenols) were used as substrates in the rea...

Two simple and selective spectrophotometric methods have been proposed for the determination of gabapentin (GBP) in pure form and in capsules. Both methods are based on the proton transfer from the Lewis acid such as 2,4,6-trinitrophenol (picric acid; PA) or 2,4-dinitrophenol (2,4-DNP) to the primary amino group of GBP which works as Lewis base and formation of yellow ion-pair complexes. The io...

Nitrophenols are present in the atmospheric gas phase and in cloud and rainwater. Their formation via aqueous-phase reactions of phenol with the nitronium ion, NO2 + , arising from N2O5 and ClNO2 partitioning into the aqueous phase, has been proposed but not verified experimentally. Here we demonstrate for the first time that gaseous N2O5 and ClNO2 partitioning into dilute aqueous solutions of ...
