Course Objectives
This course aims to provide a fundamental understanding of the chemical phenomena causing changes in the quality of surface and groundwaters, of air, as well as of waters and wastewaters undergoing treatment.
Course Content
Scope of environmental chemistry. Discussion of important relevant concepts of chemistry, and introduction of basic environmental chemical concepts including pH, alkalinity, hardness, dissolved oxygen, Biochemical Oxygen Demand (BOD), and Chemical Oxygen Demand (COD). Acid-base chemistry and its significance in environmental engineering. Dissolution and precipitation chemistry, and chemical precipitation reactions in water and wastewater treatment. Coordination chemistry, oxidation and reduction chemistry and its environmental chemical applications.
Course Learning Outcomes
The course targets the following specific outcomes:
1. Students will be able to define and solve the unknown specie concentrations in an acid-base system via writing mass balances, equilibrium expressions, charge balance and proton condition
2. Students will be able to define and solve unknown specie concentrations of an acid-base system graphically via pc-pH diagrams.
3. Students will be able to write down chemical equations to solve solubility equilibria, complexation problems.
4. Students will be able to have a basic understanding of BOD, COD, and mathematical expression of BOD.
5. Students will be able to convert specie concentrations in: M, N, mass conc., mg/L as CaCO3.
6. Students will be able to comment on ideality/non-ideality of an aqueous solution via activity coefficients, ionic strength calculations.
7. Students will be able to write down chemical reactions for buffering of acids and bases in natural aqueous systems (alkalinity and acidity concepts)
8. Students will be able to express solubility equilibria using log concentration diagrams and solve for unknown specie concentrations.
