摘要: The behavior and fate of mercury (Hg) in soil is mainly controlled by adsorption desorption processes with various adsorbents, particularly dissolved organic matter (DOM). This study was conducted to assess the effect DOM from wheat straw (DOMw) swine manure (DOMs) on Hg (II) black, red, fluvo-aquic soils China. Results showed that isotherms fitted well Langmuir Freundlich equations. maximum potential capacity three followed this trend: black > red soil. amount adsorbed significantly decreased when DOMw DOMs were added samples. Furthermore, extent which affected higher than equivalent amounts DOMs. Therefore, important determine control pollution environment.
