Open publisher page 0 citations

Abstract

Polycyclic aromatic hydrocarbons(PAHs) sorption on wetland soil in Yellow river delta was studied. The results indicated that sorption isotherms of wetland soil and samples treated by H_2O_2 were linear;PAH_s sorption isotherms could be well fitted to Linear and Freundlich equations. Different soil concentration, soil particles magnitude and system Ca~(2+) concentration influenced PAH_s sorption process. With particles magnitude and Ca~(2+) concentration increasing, adsorption capacity(K_d) of PAHs gradually decreased.
