Class Analytical Chemistry

  • Presentation

    Presentation

    The purpose of this CU is twofold: (1) brings into focus those aspects of chemistry that are particularly valuable for solving environmental problems, and (2) it lays a groundwork of understanding in the area of specialized quantitative analysis commonly referred to as water and wastewater analysis, that will serve the student as basis in all the common phases o environmental engineering practice and research.

  • Objectives

    Objectives

    The main objective of the UC is to promote understanding of the principles of analytical chemistry and its application at Environmental Engineering.
    Emphasizes, through the execution of selected practical work and the resolution of specific problems, how such principles are applied in the area of the environment.

  • Teaching methodologies and assessment

    Teaching methodologies and assessment

    Active teaching methodology places the student at the centre of the learning process. Students are encouraged to solve exercises autonomously having the opportunity to discuss with their peers the methodology to solve the problems during the class. This approach will allow students to develop critical thinking, increasing their problem-solving capacity.
