APPLICATION OF ADSORPTION FOR THE TREATMENT OF PHARMACEUTICAL INDUSTRIAL EFFLUENT: REMOVAL OF ATROPINE SULFATE (ATS) BY MULTIWALLED CARBON NANOTUBESRAI AVINASH KUMAR, BHATT JAYESH, AMETA RAKSHIT AND AMETA SURESH C.Abstract Pharmaceutically active compounds undergo metabolic processes in organisms. Significant fractions of the parent compound are excreted in unmetabolized form or as metabolites (active or inactive) into raw sewage and wastewater treatment systems. The adsorption of atropine sulfate (ATS) onto multiwalled carbon nanotubes (MWCNTs) from aqueous solutions was studied, and the influence of contact time, adsorbent dosage, pH, and concentration of ATS. The equilibrium adsorption data were found fit Langmuir and Freundlich adsorption isotherms, pseudo-first and second order kinetics and it was also concluded that intra-particle diffusion was not the only rate controlling step. |
