- 中文摘要: An experimental investigation is presented for separation of pentachlorophenol (PCP) and methyl orange (MO) from an aqueous solution by use of cetyltrimethylammonium bromide (CTAB) as a regulator in the paper capillary permeation adsorption process (PCPA). The effects of pH, concentration of CTAB, and ionic strength on the separatability of the molecules were studied. The maximum separatability of nearly 100% PCP and MO was obtained in the optimum pH range 5-11 and 7-11, respectively. The ionic strength has an appreciable effect on separatability. The recovery of PCP and MO from paper by elution with acetone:isooctane solvent gradients was also studied. The selective separation of PCP and MO admixed in aqueous solution by a developed solvent elution technique was also reported. It was believed that PCP and MO were separated as their ion pairs with CTA cations by adsorption on the fiber surface.
