Die outo-analisering van die bepaling van sulfaat en alkaliniteit in water

Abstract

Flow-injection analysis for determining total alkalinity in surface, ground and domestic water using the automated bromocresolgreen method A simple, rapid automated procedure for the colorimetric determination of total alkalinity in surface, ground and domestic water is described. The method is based on the principles of the flowinjection technique in combination with the colorimetric bromocresolgreen indicator determination. The method is suitable for the analysis of total alkalinity at a rate of up to 120 samples per hour with a coefficient of variation of better than 1,40 %. Colour and turbidity in the samples may interfere. monsters per uur (Hidrologiese Navorsingsinstituut, 1983). Gevolglik is die moontlikheid ondersoek om hierdie frekwens te verhoog en daarom is die vloei-inspuit analisetegniek (VIA) ondersoek. Hierdie tegniek is deur RuJicka en Hansen (1975) ontwikkel en is 'n cenvoudige en gerieflike konsep van konunue vloei-analise. Die tegniek is in staat om analisefrekwensie in die meeste roctine laboratoriums te verhoog.
