This course is about the colloids and surfactants. In this course, main focus is on surface tension,
adsorption isotherms, Freundlich, Langmuir and BET isotherms, surfactants, micellization, methods
of preparation of gels and emulsions, precipitation in gels, Liesegang rings, emulsifiers and breaking
of emulsions. Moreover, orientation theory, sols and their preparation, properties of sols, optical
properties of sols, determination of particle size, kinetic properties of sols, sedimentations of
suspensions, electrical properties of sols electrophoresis and electroosmosis and stability of
suspensions, molecular wt. determination of macromolecules are also part of this course. Course is
designed in a way that student may be able to prepare colloids (sols, emulsions and gels) by different
physical and chemical methods and use them in research and application fields. Knowledge about
different adsorption isotherms and the factors affecting adsorption process gives detailed
understanding of sorption mechanism which leads their command to prepare efficient sorbents to
remove pollutants and contaminations and to purify water etc.
