Treatment and Modeling of Industrial Liquid Effluent adsorption isotherm on plant-based materials

H. Chaouadi, H. Aksas, A. Elias


Abstract: Margins are not degradable due to the presence of substances (phenols, volatile fatty acids, etc.), which pose problems for the environment. In order to protect our environment, and currently know various treatment pathways such as adsorption, we studied the effects of diethylaminoethyl-cellulose (DEAE-ellulose) on the constituents of a gem and studied the adsorption power of DEAE-cellulose of phenolic compounds present in the gills of Tadmait willaya Tizi-Ouzou. The latter showed that the best adsorption conditions are simple to achieve: temperature of 22°C, direct use of the margin (Vm = 10 ml, pH = 4.5) in rather large quantities compared to that of the adsorbent (mass ratio = 10) and that the Freundlich model better represents the adsorption of the phenolic compounds of the margin on the DEAE cellulose. Infrared spectroscopy analyzes showed the complex composition of the margin in various organic constituents.  MEB- EDS microscopy analyzes revealed amorphous morphologies of the cellulose and the dry matter of the margin.
