Abstract: 

METHYL TERT-BUTYL ETHER (MTBE) HAS EMERGED AS AN IMPORTANT WATER POLLUTANT BECAUSE OF ITS HIGH MOBILITY, PERSISTENCE, AND TOXICITY. EQUILIBRIUM AND KINETIC ADSORPTION OF MTBE AND ITS MAIN DEGRADATION PRODUCT TERT-BUTYL ALCOHOL (TBA) ONTO NANO-PERFLUOROOCTYL ALUMINA PREPARED BY USING NANO-G-ALUMINA (NANO-PFOALG) WAS INVESTIGATED IN A BATCH SYSTEM. THE OXYGENATE CONCENTRATIONS WERE DETERMINED BY HEAD SPACE GAS CHROMATOGRAPHY/MASS SPECTROMETRY ANALYSES.
THE EXPERIMENTAL DATA WERE USED WITH THREE ISOTHERM MODELS (LANGMUIR, FREUNDLICH AND BET) AND TWO COMMON KINETIC MODELS (PSEUDO FIRST-ORDER AND PSEUDO SECOND-ORDER) TO DETERMINE EQUILIBRIUM AND KINETIC PARAMETERS. CONSIDERING THE CORRELATION COEFFICIENT, ALL THREE ISOTHERM MODELS WERE OBTAINED GOOD CORRELATION BETWEEN THE EXPERIMENTAL AND PREDICTED DATA. THE KINETIC DATA PROVED A CLOSER fiT TO THE PSEUDO-SECOND ORDER MODEL. VALUES FOR THE RATE CONSTANT, K2, WERE OBTAINED FOR MTBE AND TBA ADSORPTION, AS 0.00226 AND 0.023 (G MG-1 SEC -1), RESPECTIVELY. RESULTS REVEAL THAT PFOALG IS AN EFFECTIVE ADSORBENT FOR METHYL TERT-BUTYL ETHER AND TERT-BUTYL ALCOHOL.
