Humic substances have natural surfactant characteristics and have a relatively high affinity for pentachlorophenol (PCP). However, humic substances cannot be loaded into bentonite (Bent) via intercalation because of their larger size. In the present study, a humin-like substance (HuLS) was prepared by polycondensation reactions of humic precursors, such as glycine and catechol, and the product was...
An allophanic soil (AS) catalyzed the formation of dark-colored polymers via polycondensation reactions between catechol and glycine. The organic carbon content of the AS was increased from 0.16% to 1.3%, indicating that some of the dark-colored polymers had been adsorbed to the AS. The characteristics of the dark-colored polymers adsorbed on the AS were similar to those of a humin that is not extractable...
