- 中文摘要: 2,4-Dichlorophenol (2,4-DCP) and 2,4,6-trichlorophenol (2,4,6-TCP) by the use of cetylpyridinium chloride (CPCl) as a regulator was studied for their separation by the paper capillary permeation adsorption (PCPA) separation technique. The effect of pH, the type of PCPA treatment, the concentration of cetylpyridinium chloride, and various inorganic salts on the separatability has been investigated. A nearly 100% separatability was obtained at pH values 5-11 and 5-11, respectively, for 2,4-dichlorophenol and 2,4,6-trichlorophenol when cetylpyridinium chloride was present. It was confirmed that 2,4-dichlorophenol and 2,4,6-trichlorophenol are separated by adsorption on the fiber surface as ion pairs at the pH. Addition of inorganic salts decreases the separatability.
