Abstract

The interactions between three metals (Cu²⁺, Fe³⁺, and Al³⁺) and dissolved organic matter (DOM) from the effluent of the secondary sedimentation tank of wastewater treatment plant were investigated using three-dimensional excitation-emission matrix (EEM) fluorescence quenching coupled with self-weighted alternating trilinear decomposition (SWATLD) analysis. Two main components in the DOM were identified by the EEM analysis: proteins at E _x /E _m (230-235/345-350) nm and humic-like substances at E _x /E _m (340-350/425-430) nm. The conditional stability constant (log K _c) was calculated to evaluate the metal complexing properties of DOM by Ryan-Weber model. The two components in DOM were strong ligands for the three metals based on the conditional stability constants, with an order of Cu²⁺ > Al³⁺ > Fe³⁺. Results indicated that the DOM played an important role in the environmental behavior of metals.
