71618: Introduction to Soil Chemistry

Course Level: undergraduate
Concept of the course: Demonstration of the interrelations between chemistry of soil components and soil processes, and between solid and liquid phases in soils. The importance of interfacial reactions is emphasized. 


Ongoing Research

DOM–affected behavior of manufactured nanoparticles in soil-plant system

Adsorption and transformation of organic contaminants by clays

Adsorption and transformation of inorganic oxyanions and organic anions by clays and oxides
