- Abstract
- The study of the processes of sorption of various chlorophenolic compounds from aqueous solutions by high-moor peat and products of its sequential disassembly was carried out. Compounds with different degrees of chlorine substitution were used as model chlorophenolic compounds: 2,4-dichlorophenol, 2,4,6-trichlorophenol, and penta-chlorophenol. According to the results of chromatographic determination, it was established that the degree of binding of chlorophenolic compounds by the studied materials increases in the series: pentachlorophenol (10.9-15.5 µg/g peat, or 31.4-44.7%)-2,4,6-trichlorophenol (16.3-26.3 µg/g peat, or 47.6-76.7%)-2,4-dichlorophenol (19.6-34.6 µg/g peat, or 56.8-100%). An increase in the pH medium leads to an increase in the degree of dissociation of chlorophenolic compounds and their mobility, and ultimately to a decrease in the degree of their binding. The effect of pH is most pronounced for 2,4-dichlorophenol, which is characterized by the maximum pKa value.
