Effect of Al13 Polycation Grafting on Apple Wastes Activated Carbon That Have A Porous Structure

Abstract

Using physical activation, modified apple wastes with Al 13 polycation were utilized such a feedstock's for activated carbon production .thence, The characteristics of synthesized materials were: N 2 adsorption/desorption , Scanning electron microscopy, and Fourier-transform infrared analyses. AS a beginning, one studied the effect of Al 13 grafting on textural and chemical surface characteristics of activate,d carbons-Al 13 generated . The increasing Al 13 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 m 2 /g, micropore area of 400 m 2 /g and microporous volume of 0.185 cm 3 /g is the best surface area).ALSO The methyl orange adsorption performance of the received adsorbent was investigated to identify the role of Al 13 , 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 Al 13 grafting improved the 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-Al 13 founded to be an efficient material for anionic dye removed from wastewater.
