TREATMENT and DISPOSAL of INDUSTRIAL WASTEWATER
12 credits
Prof. Milena Rizzo
1st and 2nd Semester
A.A. 2012-2013
Objectives
The course provides the theoretical and practical tools for conducting qualitative
analysis and recognition toxic as inorganic elements or organometallic and organic
compounds
The student will acquire the skills needed to perform manual and instrumental analysis
in the laboratory.
Prerequisites
Knowledge of General and Inorganic Chemistry, Organic Chemistry, Chemical
Toxicology.
Teaching methodology
The teaching consists of lectures, seminars and laboratory exercises.
During the course and before the practical laboratory work, are carried out "test in
progress" as multiple-choice tests and short questions, in order to assess the level of
knowledge acquired in the theoretical arguments presented.
The laboratory exercises are individual when applied to the analysis of species of
toxicological interest. Furthermore, group exercises for analysis of simple mixtures by
means of instrumental methods are proposed.
Examination
The exam consists of a written paper tends to test the knowledge of the proposed
topics and the ability to link between the concepts acquired, as well as the ability to
represent phenomena and chemical reactions subject of toxicological analysis.
