STUDYING KINETICS AND MECHANISM OF Cr(VI) ABSORPTION BY PANi MATERIALS SYNTHESIZED WITH RHODOMYRTUS TOMENTOSA WATER EXTRACTS

Abstract

  In this study, the aqueous Cr(VI) absorpsion on modified polyaniline materials(MPM) were investigated. The MPM was synthesized between Aniline and Ammoniumpersulfate (APS) as an oxidant in acidic medium H2SO4 1M/HCl 1M withRhodomyrtus tomentosa's extraction in water and Rhodomyrtus tomentosa'sextraction residues using as adsorbent, respectively. The mechanism of Cr(VI)absorption ions on the MPM were compared and discussed herein.
