| Abstract/Summary |
The retention efficiency of phenol and eight derivative compounds on both Sephadex and Dowex anionic exchangers is evaluated, including chlorophenols (2-chlorophenol, 4-chlorophenol, 4-cresol), nitrophenols (2-nitrophenol, 4-nitrophenol, 4-methyl-2-nitrophenol), and naphthols (1-naphthol and 2-naphthol). The retention efficiency of these phenolic compounds on Sephadex QAE A-25, Sephadex DEAE A-25, and Dowex 1 × 8 (200—400 “mesh”) is studied from solutions containing all these compounds simultaneously. Mixtures of the compounds are passed in-line through minicolumns of these polymeric supports by means of a peristaltic pump and the variables influencing the retention of phenols on the supports are studied for each compound as well as the nature, concentration, and volume of the eluent. The separation, identification, and determination of the eluate composition was carried out by HPLC and the detection of the analytes was performed using a dual UV detector tuned at 215 nm and 230 nm. Results showed different levels of retention efficiency.
