The training of chemistry teaching students in systematic professional work is an integral part of their pregradual preparation. Its fundamentals are given in all branches of chemistry, but laboratory training in analytical chemistry, demonstrating application of instrumental methods, offer appropriate opportunities. The tasks are constructed to emphasize not only the principles of the methods but also their utilization in environmental analysis. An enhanced interest of students in the professional work appears, which results in their participation in projects and is also reflected in subjects of their diploma theses.
