The major purpose of Environmental Organic Chemistry is to familiar students with the types, functional groups, and basic properties of organic pollutants. Based on the reaction mechanisms and their derivatives, the degradation, transformation, translocation, and transportation processes of organic pollutants in natural environment and particular conditions will be discussed. It is expected that students will recognize the related processes of organic pollutants during future research, analysis and treatment of environmental organic pollutants. The contents of this course will focus on (1) classifications and related characteristics, (2) basic reaction principles, (3) environmental fates of organic pollutants. (1) Classifications and related characteristics: include organics classification, physical and chemical properties, vapor pressure, water solubility and activity coefficient, air-water partitioning, organic solvent-water partitioning, bioconcentration, diffusion, sorption and desorption, (2) Basic reaction principles: hydrolysis (hydrolysis kinetics, hydrolysis reaction mechanisms, nucleophilic substitution reactions, catalysis), reduction (reductive transformation pathways, reductive kinetics), environmental oxidation (molecular oxygen, hydrogen peroxide, surface reaction, thermal oxidations), reactions with disinfectants, photochemical reactions (direct and indirect photodegradation), biotransformation, (3) Environmental fates of organic pollutants: the carbon cycle, organic translocation, organic transformation, effects of L-G-S phases on organics.
