A novel indirect electrochemical protocol for the electroanalytical detection of phenols is presented for the first time. This methodology is demonstrated with the indirect determination of the target analytes phenol, 2-chlorophenol, 4-chlorophenol and 2,4-dichlorophenol through an electrochemically adapted optical protocol. This electrochemical adaptation allows the determination of the above ...

Fertilizer plant waste carbon slurry has been investigated after some processing as an adsorbent for the removal of dyes and phenols using columns. The results show that the carbonaceous adsorbent prepared from carbon slurry being porous and having appreciable surface area (380 m2/g) can remove dyes both cationic (meldola blue, methylene blue, chrysoidine G, crystal violet) as well a...

Abstract Background: Photocatalytic process is used as a suitable method for o-chlorophenol removal. In this study, the efficiency of a mixture of modified fly ash and TiO2 nanoparticles in photocatalytic removal of o-chlorophenol was evaluated. Methods: After acid washing of fly ash, the absorbent was oxidized with potassium permanganate. ...

The pharmacokinetics of p-chloronitrobenzene (p-CNB) in human subjects suffering from acute poisoning was studied from the urinary excretion of p-CNB metabolites. The time course for excretion of five metabolites--2-chloro-5-nitrophenol,N-acetyl-S-(4-nitrophenyl)- L-cysteine, 2,4-dichloroaniline, p-chloroaniline, and 2-amino-5-chlorophenol-were determined by reversed-phase HPLC analysis of urin...

ONE of the major problems associated with the disinfection of water supplies by chlorination is that the organoleptic properties of the chlorinated water may be increased. This malodorous water is often produced by a reaction between the added chlorine and trace concentrations of organic compounds present in the water. By far the most notorious of the organic compounds found in water which incr...

This paper, the second in a series concerning the use of indicator dyes to study the reactions of organic acids and bases in organic solvents, deals with halogen derivatives of phenolsulfonephthalein. Spectrophotometric data are given for mixtures of bromocresol green, bromophenol blue, iodophenol blue, and tetrabromophenol blue with primary, secondary, and tertiary aliphatic amines in benzene;...
