Optimization of conditions for sorption preconcentration of phenol from aqueous solutions on activated carbon

Abstract

The paper considers the regularities of the retention of phenol on widely available brand activated carbon BAU-A and surface-layer carbon-polytetrafluoroethylene adsorbents based on it. Mapped the efficiency of sorption preconcentration on both types of sorbents, the optimum mass content of carbon on PTFE, and also optimized the conditions for rapid sorption preconcentration of phenol from aqueous solutions, such as the geometrical dimensions of the column, the flow rate of the water sample through the adsorption column, an organic solvent for desorption. Optimization of conditions for preconcentration was conducted with a focus on further quantification of phenol by HPLC with most common and commercially available spectrophotometric detector.
