An efficient cheap source of activated carbon as solid phases for extraction and removal of Congo Red from aqueous solutions

The present study reported the preparation of solid phases from various available and cheap natural sources represented by activated carbon to remove polluting dye Congo Red (CR). Activated derived leaves Consocarpus plant (C/AC) Ziziphus Spina-Christi (Z/AC) Myrtus (M/AC) chemical activation. were diagnosed examined using FTIR, FESE, XRD. results indicated that best amount for phase was 0.25 g three used against dye, optimal concentration CR 100 mg L-1, optimum acidity function equal 5 with a volume 25 mL, as optimization experiments flow rate eluting solution 0.5 ml min-1. elution processes carried out several solvents different in polarity it found 8 mL DMSO achieved percentage recovery (%R). Also, adsorption capacity based on conditions obtained applying Langmuir Freundlich isotherm models, qmax, according model, (21.74, 23.53, 22.17) g-1 (Z/AC), (C/AC), adsorbents, respectively.
