Course Description:  Pollutant mobility, toxicity, and amenability to treatment in the environmentdepend on the physical and chemical reactions the pollutant undergoes in the environmental

systems. This course introduces fundamental principles and processes that govern the fate andtransport of these chemicals in pristine and polluted soil, surface, and groundwater environments.

The course examines the equilibrium and kinetics of chemical reactions relevant to environmentalsystems. The reactions involve partitioning between phases and chemical transformations.Partitioning reactions focus on gas-liquid, liquid-liquid, and liquid-solid partitioning of chemical

contaminants. Transformation reactions include hydrolysis, oxidation-reduction, and photolysis

reactions. For each reaction, the fundamental molecular interactions affecting the process are firstexamined. The quantitative application of the reaction to environmental behaviour is then

 presented.

Topics covered include acids and bases, mineral solubility, carbonate chemistry, chemicalspeciation, redox reactions, adsorption and ion exchange, and the speciation, mobility, and toxicityof metals. Furthermore, the theory and application of the physical and chemical processes of

coagulation, flocculation, sedimentation, softening, filtration, and disinfection in water and

wastewater treatment is presented. Principles that can be used in the analysis and modeling ofenvironmental engineering processes, including material and energy balances, mass transfer, andreaction engineering are elucidated.

Course Objectives:  After completing this course, students should be able to:

•  Quantitatively and qualitatively describe equilibrium and kinetics of chemical partitioning

and transformation processes.

•  Estimate chemical properties based on chemical structure.

•  Apply knowledge of chemical properties to the interpretation of chemical behaviour in an

environmental system.

•  Communicate an understanding of physicochemical principles in multiple formats.

Course Responsibilities: Course grades will be determined based on in-class practice problems,quizzes, HW problem sets, term paper and midterm and final exams:

In-class problems and quizzes: 20-25%

HW Assignments 10%

Term Paper/ Project 15-20%

Exams: 50% (20% mid-sem; 30% end-sem)

 In-class Problems: Typically, 1-2 problems will be discussed on the central theme in every class.After being told of the steps to do these problems, students will be expected to complete and turn in

these problems for evaluation. Out of the total such evaluations, the worst two scores will be

dropped and the rest of the scores would be considered towards final grade. The idea is to

encourage students to participate and attend classes. It is recommended to maintain a register to filenew or used pages used for solving problems.

5-6 announced/ surprise quizzes will be conducted. Scores of all, except the worst one,

will be considered for final grade.

 Problem Sets: Four problem sets will be assigned during the semester, and students will have to

submit them for evaluation by a cut-off date. No late submissions would be acceptable. Latehomework will be accepted until three days after the due date, but the maximum credit would be

scaled down with a penalty of -20% per day (including weekends and holidays). Late homework

must be turned in to the instructor or TA in person unless other arrangements have been made. Nohomework will be accepted on weekends and IITK holidays.

 Exams: Two exams will be given. Although focused on the most recent material covered,students will need to recall information from the pre-mid sem portion (~20%) to complete the end

sem successfully.

Term Paper/ Project: Students will prepare a term paper that critically reviews the physicochemical principles of an environmentally-relevant process. Groups of 3-4 students will be

assigned by the instructor and will be asked to select a topic. The term paper will include

intergroup and intragroup peer evaluations. Details will be provided early in the sem.

Grading: Final grades will be determined by the instructor. There will be relative grading withrespect to peers as well as with respect to the previous year’s scores. Attendance and regularity

may be used to decide marginal cases between two grades.

Homework Policy: Students are encouraged to discuss the course material, both inside and

outside of the class and can work together on problem sets and in-class problems. However, eachstudent is expected to turn in his/her own work (verbatim solutions submitted by two or more

students are not acceptable, will get zero credit and face possible disciplinary action) 

Exam Policy: Please do not miss an exam. If you miss an exam and provide me with an

acceptable written excuse, I may choose to schedule an oral or written make-up exam or assign

50% of your grade to the other exam.

Academic Integrity: All students are expected to adhere to high standards of academic integrity

of IIT Kanpur. If you have any doubts or questions about the policies, please ask the instructor.
