Physical and chemical modification of Alhagi maurorum waste for enhancement removal safranin-O from aqueous solution

Abstract

On the way to accomplishing a supportable chemical and physical processes, Alhagi maurorum a low cost, natural waste and available material was explored to operate as an adsorbent for removal safranin-O in the industrial effluents. In addition to enter some of the enhancement such as acidic and thermal activation. The work was achieve in a batch with same dye concentration, adsorbent dosage, and contact time. Firstly, the removal of dye was very rapid, then step by step reduced representative diffusion into the inner of the adsorbent particles, increasment of the removal Sfranin-O dye percentages, taken the following sequences:Acidic or wet activation 97% > thermal or dry activation 90.4 > orginal or non activation adsrpent 84.6%.
