Določevanje agresivnega CO [spodaj] 2 v pitni vodi

diplomsko delo

Abstract

Voda mora biti za potrebe ljudi optimalne kakovosti. V njej je raztopljenih veliko organskih in anorganskih snovi, ki lahko pod določenimi pogoji tvorijo spojine, ki povzročajo nezaželene spremembe, predvsem v vodovodnem omrežju. Med njih spada CO2, ki v vodo največ prehaja iz zraka, se v njej topi in tvori šibko ogljikovo kislino. Do neke mere je to optimalno za vzpostavitev karbonatnega ravnotežja. Voda, ki vsebuje preveč ogljikovega dioksida je agresivna in povzroči korozijo cevi, ventilov ter druge poškodbe vodovodnega omrežja. V diplomski nalogi sem s postopkom validacije metodo za določevanje agresivnega CO2 uvedla v laboratorijsko delo in jo preverila na realnih vzorcih pitne vode v celjskem vodovodnem omrežju.

Secondary title:	Content of aggressive CO2 in Celje water supply network
Secondary abstract:	For human use, water needs to be optimal quality. It contains many organic and inorganic substances that can form harmful compounds under certain conditions. One of many is CO2, which passes into water from the air, dissolves in it and forms week carbonic acid. To some extent, this reaction is optimal for establishing carbonate equilibrium. Water that contains too much carbon dioxide is aggressive and causes corrosion of pipes, valves and other damage to the water supply network. In this research process I introduced the method for determining aggressive CO2 into laboratory work with the validation and tested it on real samples of drinking water in the Celje water supply network.
