| Abstract: | The Yekuling detention and degradation in the environment of rice fields were studied. The photolysis rate of Yekuling in ultraviolet light was greater than that in sunlight. The degradation of Yekuling in the field was faster than that in the laboratory. The hydrolysis and microbial decomposition in water played a major role in Yekuling degradation. Yekuling was mainly remained at the surface layer of soils because of the strong adsorption.
A significant correlation was revealed between the organic content in soil and the rate of adsorption. The rate of adsorption was also influenced by the type of soils and the amount of clay in soil. The degradation pattern of Yekuling in the rice field can be expressed as y = ae-bt. |
