4. Description Abstract

In this work, Raw Pomegranate Peel (RPP) was used as an adsorbent or the removal of anionic (EBT, DB71) and cationic (MG, MB) dyes from water. FT-IR spectroscopy showed that RPP has (-OH) and (-COOH) functional groups. The RPP powder shows an adsorption capacity of 81% for MB and 83% for MG obtained at pH= 7, and 69% for DB71 and 62% for EBT at pH3, in 60 min of contact for an initial dye concentration of 50 mg.L-1 and an amount of RPP of 0.1 g at a temperature of 298 k. The results of the isothermal analysis indicate that the Langmuir isothermal model described the adsorption of the studied dyes on RPP, and the sorption kinetics data are consistent with the pseudo-second-order model. The adsorption on a solution simulating real conditions shows a promising application in wastewater treatment.
