The improvement of information and measuring system of halogen control in drinking water

Abstract

Consideration of currently used methods for determining the most important indicators of natural water quality, such as the content of chlorides, fluorides, iodides, bromides, petroleum products, phenols, anionic surfactants, heavy metals, inorganic nitrogen and phosphorus compounds and the like showed that the whole set of methodological tasks for determining these indicators can be solved in flow analysis using three detection methods: photometry, fluorometry and ionometry. When improving the measuring unit, it is envisaged that it is universal in purpose: both for autonomous devices for equipping analytical laboratories, and for the module of the individual channel of automated multi-channel systems of continuous information and measuring control. Ion-selective electrodes were used as the basis of the measuring unit in the flow-injection analysis of the composition of drinking water for the content of chlorides and fluorides. Statistical processing of measurement results with their visualization and interpretation using Schuhart charts was performed.
