Abstract Established applications of emulsion liquid membranes (ELM) refer to refining in hydrocarbons and hydrometallurgical processing, rehabilitation of poisoned patients. In this work we investigated the separation of aromatic compounds of biological interest, more often encountered as intermediates in dyes and drugs industry: aniline, nitrobenzene, ortho and para-toluidine, using emulsion liquid membranes. The experimental results showed that in the case of basic substances separation t...

Abstract A study of a classical BLEVE fireball model associated with a toxic Puff release one was made in order to evaluate the influence of accident conjugate conditions on its consequences in two neighbouring industrial plants. The possible occurrence of the Domino effect is also exemplified for the approached chemical complex including two sensitive neighbouring chemical plants including tubular reactors for catalytic oxidation of butane to maleic anhydride and catalytic hydrogenation of ...

Aniline is a priority pollutant, which is known as a toxic organic pollutant released as effluent from several industries. Several physicochemical methods have been used for degradation of this pollutant. In this study, photocatalytic degradation of aniline from synthetic wastewater by ZnO nanoparticle was considered. The effects of different variables, such as irradiation time, the amount of photocatalyst, initial pH values and initial concentration of pollutant on the photodegradation of an...
