Abstract:

Using physical activation, modified apple wastes with Al13 polycation were utilized such a feedstock’s for activated carbon production .thence, The characteristics of synthesized materials were: N2 adsorption/desorption , Scanning electron microscopy, and Fourier-transform infrared analyses.AS a beginning, one studied the effect of Al13 grafting on textural and chemical surface characteristics of activate,d carbons- Al13 generated . The increasing Al13 content has major inffluences on the porous structure of the prepared activated carbon; it causes more structurale and intensifies the surface zone and the pore volume (484 m2/g, micropore area of 400 m2/g and microporous volume of 0.185 cm3/g is the best surface area).ALSO The methyl orange adsorption performance of the received adsorbent was  investigated to identify the role of Al13, especially its particular structure and high positive charge (+7). Adsorption performance of the grafted activated carbon was significantly enhanced. Raising charges at carbons materials surface by Al13 grafting improvedthe methyl orange adsorption kinetics. The adsorption data was relevant to Langmuir, Freundlich and Temkin models. The results indicated that the adsorption data belonging better to the Langmuir isotherm model. The prepared activated carbon- Al13 founded to be an efficient material for anionic dye removed from wastewater.
