Vision

The Department of Chemistry tries to promote the view of Chemistry as a human enterprise and not solely as a rigid body of knowledge. The total picture - from raw materials through beneficiation to research, including management aspects - is presented. Therefore, our courses provide a firm foundation in chemical ideas, processes, and applications and the context of Chemistry in society. Experimental and field-work form an integral part of all courses and self-initiated research is encouraged at postgraduate level. The department offers courses in pure, applied, and environmental chemistry, as well as the opportunity to do postgraduate research up to doctoral level.

Statement of purpose


The Department of Chemistry is dedicated to the empowerment of the community it serves by providing chemical training needs through excellence in teaching, research and community engagement projects. We are committed to furthering knowledge and understanding of chemical systems and their functioning in the environment, and to inculcate values conducive to the sustainable development of these systems.

This Commitment is pursued through
:

  • Promotion of scholarship at all levels;
  • Teaching in formal courses, community service and consultancy;
  • Research, which may be fundamental or applied to the solution of environmental, human or chemical problems.


To reach its goals, the department seeks to:

  • Develop courses that maximally satisfy the requirements of employers and the needs and aspirations of students by means of regular contact with Industry;
  • Present courses in cooperation with Industry and other tertiary institutions;
  • Develop a research programme appropriate to the University's situation;
  • Keep the public informed of important events of a chemical nature;
  • Promote the image of Chemistry through various outreach activities.


Overview & History

The Department of Chemistry became operational in January 1984 with the appointment of Prof T van Ree as the first permanent staff member and head of the department, teaching several First, Second, and Third Year courses. The University of Venda has had to cope with financial constraints since its inception, but the Department was able to attract high quality staff, so that by 1987 there were already five academic staff members and a Chief Laboratory Technician. The first Honours candidates graduated in 1988, followed by the first Masters candidate in 1995 and the first doctorate in 2012. Currently, the Department is relatively well equipped, with a state of the art 400 MHz NMR spectrometer being installed in 2011. Apart from eight full-time teaching staff, there are now also two laboratory technicians, a full-time NMR operator, and several part-time staff members.

The chemistry group currently enrols an average of seven Honours students every year, who are fully involved in the research programme. A further seven Masters’  and three PhD`s students are currently enrolled, in a variety of fields covering natural products, organic synthesis methodology and modelling, environmental analysis and computational chemistry.

The Department of Chemistry has identified three major research niches that can capitalize on our present strengths. These are the broad areas of (environmental) analytical chemistry and natural products chemistry, with both analytical and synthetic topics being addressed in these areas, and computational chemistry, mostly focusing on the computational study of biologically active molecules. The Department is especially involved in research in the areas of Natural Products Research, Organic Synthesis, and Molecular Modelling.
