Aquatic Microinterface Group(AMIG)

The main focus of our group is on the physico-chemical processes of the aquatic particulates and sediments concerning the water quality in both natural and water treatment systems, with emphasis on the innovative theoretical study of the basic environmental micro-interfacial processes and to the development of modern water quality science and technology with high efficiency as well. The research involves the interfacial structure characterization of the aquatic particulates and sediments including their reaction mechanisms with pollutants, the adsorption process and chemistry, the coagulation-flocculation processes and the chemistry of new water treatment reagents and material, as well as the mathematic modeling of water treatment and water quality transformation processes (e.g. surface complexation model and the sediment quality criteria). Our work aims to provide solutions for water quality problems in both natural waters and water treatment units.

Aquatic particulates are fine particles suspended or dispersed as aquasols in the aquatic environments that comprise the aquatic micro-interfacial systems. With the enormous specific area and the ample reactive functional groups,aquatic particulates interact with aquatic pollutants (e.g. heavy metals, organic contaminants and so on) via a variety of interfacial reaction processes,which play a decisive role in the water quality of both natural aquatic systems and water treatment processes. An in-depth investigation into the interfacial structures, speciation and their transformation, interacting mechanism, reaction kinetics and the calculation model becomes the hot topic and frontier in the Environmental Aquatic Chemistry and Water Quality Science and Technology.
