摘要

Humic acid adsorption by allophane, ferrihydrite, activated charcoal and micro charcoal were studied to clarify the mechanisms involved in the accumulation of humic substances in Andisols. Adsorption envelopes indicated that: (1) the adsorption patterns of humic acid on these materials from equilibrium pH 4 to 6 showed that the amount of humic acid sorbed was the largest for allophane followed by activated charcoal, ferrihydrite and micro charcoal; (2) there were many differences between activatedcharcoal and micro charcoal in regards to their humic acid adsorption properties; and (3) the amount of active Al was much larger than that of micro charcoal in Andisols. It was concluded that active Al plays an important role in the accumulation of humic substances in Andisols.
