Abstract: In order to understand the characteristics of dissolved organic matter(DOM) adsorbing heavy metals in wetland soil, the effect of two exogenous DOM(Carex DOM and humic acid HA) on the adsorption of Pb2+ and Cd2+ in wetland soil was explored by using the batch balance method and by utilizing the technology of ultraviolet-visible absorption spectroscopy.The results showed that the UV absorption intensity of HA was significantly greater than that of Carex DOM,and the molecular... More
