OBJECTIVE:

  • The objectives of the course are to study the basics of environmental chemistry, chemical reactions involved in water and electro kinetic properties.

UNIT I INTRODUCTION                                                   9

Fate of Chemicals in environment, Stoichiometry and mass balance-Chemical equilibria, acid base, solubility product(Ksp) order of reactions Chemical kinetics, Principles of green chemistry.

UNIT II AQUATIC CHEMISTRY                                        9

Water quality parameters- environmental significance and determination; chemicals in water and wastewater, volatilization, hydrolysis, photochemical transformation– Degradation of chemicals-Metals, complex formation, oxidation and reduction , pE – pH diagrams, redox zones – sorption- Colloids, electrical properties, double layer theory, environmental significance of colloids, coagulation .

UNIT III ATMOSPHERIC CHEMISTRY                             9

Atmospheric structure –-chemical and photochemical reactions – photochemical smog. Ozone layer depletion – greenhouse gases and global warming, – Acid rain- origin and composition of particulates. Air quality parameters-effects and chemistry in air pollutants analysis.

UNIT IV SOIL CHEMISTRY                                              9

Nature and composition of soil-Clays- cation exchange capacity-acid base and ionexchange reactions in soil – Agricultural chemicals in soil-Reclamation of contaminated land; salt by leaching- Heavy metals by electrokinetic remediation.

UNIT V ENVIRONMENTAL CHEMICALS                        9

Heavy metals-Chemical speciation –Speciation of Hg &As- Organic chemicals- Pesticides, Dioxins, PCBs ,PAHs and endocrine disruptors and their Toxicity- Nano materials, CNT, titania, composites ,environmental applications

                                                                                                       TOTAL:45 PERIODS

OUTCOMES:

The students completing the course will have

  • an insight in to the chemical reactions in water, air and soil environment.
  • the ability to apply chemistry principles in analysing pollution of water, air and soil environment.
  • an understanding on the fate of chemicals on the environment and suggest relevant interventions.
