Physical-Chemistry Analyses

Basic concepts related to chemical solutions, including:
i) Preparation of solutions
ii) Standard solutions,
iii) Reactions of acid-base, precipitation, complexation and oxidation reduction
(iv) Volumetric techniques

In order to meet the proposed objectives for the course and to confer the skills defined, exposure classes will be taught about environmental monitoring and theoretical principles that underlie the different methods of analysis of water quality and wastes. A set of 14 laboratory classes will be given, in which will be run the different analytical parameters.
The practical component will be evaluated continuously, having as elements of assessment, the conduct and quality of reporting (presentation and discussion of results). The assessment of the theoretical
component will consist of two written tests.
The final grade is calculated by a weighted average of the classification obtained in the theoretical modules
(75%) and of the practical component (25%).

1- Enumeration and description of the physicochemical parameters for assessing the quality of an ecosystem and a water supply, assessment of pollution load and quality of discharges and fertilizer value of waste.
2- Demonstration of knowledge of the theoretical principles of different analytical methods.
3- Mastering of analytical methodologies that can be used to control the quality of ecosystems, water and wastewater and analyze the results
4- Knowledge of legal requirements.

1- Environmental monitoring.
2- The impact of waste discharge into the environment. Study of the environmental meaning of each of the physicochemical parameters to be analyzed. Legal requirement.
3- Theoretical principles of the main analytical methods for evaluating the quality of water and wastes:
gravimetric methods, volumetric and instrumental methods -potentiometry, molecular-visible spectrophotometry / Ultra-violet (UV), flame atomic absorption and graphite furnace, spectrophotometry emission flame and inductive coupled plasma (ICP), gas chromatography (GC) and high pressure liquid chromatography (HPLC). Elimination of interference in analytical methods. Quantitative analysis. Equipment.
4- Evaluation of analytical results from different analytical parameters of the water quality and wastes.
