Removal of carmoisine-E112 using different types of porous media

Abstract EN

All over the world the presence of heavy metals in water supply sources has been raising great concern in terms of public health since many epidemiologic studies confirm the potential carcinogenic effect of these pollutants at concentrations above acceptable standards.

The purpose of the research is to manufacture porous medium suitable adsorption and remove Carmoisine (E-122).This work includes two tracks; the first track explains the batch model results, while the other track contains continuous flow system.

The results of batch mode experiments have been presented to examine the efficiency of removing carmoisine E112 by activated ceramic.

In this system, the effects of pH, activated ceramic amount, initial concentration of the activated ceramic, and agitation speed and equilibrium time on adsorption efficiency are studied.

The continuous flow system experiments, have been carried out during period from April/2014 to May /2014 , to examine the efficiency removal of carmoicine E112 by six types of media one of them is non-uniform which is the activated ceramic and the others are uniform (silty clay, sandy clay, composite porous media, porculinite, gravel and ceramic).
