Phenol

This experimental work studies photocatalytic degradation of phenol. The semiconductors used were zinc oxide (ZnO) and three commercial titanium oxides (TiO2) (Dégussa P25, TiO2-A1 and TiO2-A2). The rate of removal was greater for Dégussa P25 and ZnO. To understand the difference between photocataly

Reverse osmosis performance for certain low molecular weight organic solutes in water, such as phenol and its derivatives, is markedly different from that of simple aqueous salt solutions. The unusual solute–membrane affinity reverse osmosis behaviour of phenol–water–cellulose acetate system has bee

Application of membrane techniques (pervaporation and membrane-based solvent extraction) and adsorption tothe removal of phenol from solutions modelling wastewater from phenol production by cumene oxidation processwas investigated. The transport and separation properties of composite membranes PEBA,

In this study, the membrane extraction of phenol-4-aminoantipyrine complex with the series of aliphatic alcohols was investigated by monitoring the efficiency of the process. A commercial polysulphone hollow-fiber membrane module was used in all experiments. The effects of feed and extragent stream

In this paper the multistage membrane pertraction (simultaneous extraction and reextraction) of phenol with linear monoalkyl cyclohexane (lMACH) as a carrier and sodium hydroxide solution as a strip, in laboratory scaled pertractors with polysulphone hollow-fiber membranes, was investigated. Two typ

This article describes a novel process for recovery of aromatic amines and phenolic compounds form wastewaters, the membrane aromatic recovery aromatic system (MARS). Laboratory work on wastewaters containing aniline and phenol will be presented, including data demonstrating removal and recovery of
