Abstract

IN THE CURRENT STUDY, SORPTION OF CONGO RED DYE (CR) FROM AQUEOUS SOLUTIONS, USING COPPER OXIDE/SAWDUST NANOCOMPOSITE (TERMED AS CUO/SD NC) HAS BEEN INVESTIGATED. X-RAY DIFFRACTION (XRD) AND SCANNING ELECTRON MICROSCOPY (SEM) TECHNIQUES WERE USED FOR CHARACTERIZATION OF THE PREPARED ADSORBENT. SORPTION EXPERIMENTS WERE PERFORMED USING FIXED-BED COLUMN SYSTEM. THE EFFECTS OF SEVERAL PARAMETERS, SUCH AS PH, INITIAL DYE CONCENTRATION, FLOW RATE, AND BED DEPTH ON THE SORPTION OF CR DYE HAVE BEEN STUDIED. THOMAS AND THE BED-DEPTH SERVICE TIME MODEL (BDST) WERE APPLIED FOR ANALYSIS OF SORPTION DATA AND ESTIMATING OF SORPTION CAPACITY AND COLUMN PERFORMANCE. THE RESULTS SHOWED THAT THOMAS MODEL WAS FOUND SUITABLE FOR THE NORMAL DESCRIPTION OF BREAKTHROUGH CURVE UNDER THE EMPLOYED EXPERIMENTAL CONDITION AND FROM THE REGRESSION ANALYSIS, SORPTION DATA WERE IN GOOD AGREEMENT WITH BDST MODEL. THE RESULTS OF THIS STUDY INDICATED THAT THE EXHAUSTED CUO/SD COLUMN CAN BE EASILY REGENERATED USING DILUTE NAOH SOLUTION WITH HIGH PERFORMANCE (>99%). THE RESULTS OF THIS STUDY ALSO INDICATED THE SUCCESSFUL APPLICABILITY OF THE CUO/SD NANOCOMPOSITE AS A VERY EFFICIENT ADSORBENT FOR THE REMOVAL OF ANIONIC DYES SUCH AS CONGO RED FROM AQUEOUS WASTES.
