Interest in the automation of titration arise from the fact that many acid-base titrations in the process industries rely on manual titration which is time consuming. Miniaturization of these titration processes becomes attractive because of the reduced reagent consumption. These industries must produce higher quality products economically and in a friendly environment. Due to its ease of automation, ability to handle concentrated solutions and simplicity, the application of sequential injection titration is an ideal tool in process effluent streams, food industries, beverage industries and production plants. The sequential injection titration system was optimised with respect to all instrumental parameters of the system and applied for acid-base titrations. The results obtained showed high reliability and reproducibility. The system is fully computerised, inexpensive and suitable for on-line monitoring. / Dissertation (MSc (Chemistry))--University of Pretoria, 2006. / Chemistry / unrestricted
