As a part of preliminary studies, the possibility of quantitative oxidation of aldehydes to carboxylic acids and their determination by isocratic ion chromatography with conductometric detection has been tested.
Validated isocratic ion chromatography method with suppressed conductivity detection has been developed for the simultaneously determination of common inorganic anions (F-, Cl-, NO3-, PO43-, SO42-), as well as formate and acetate. Liquid samples originate from absorption of gaseous by-products from coal combustion with and without the addition of medium-density fireboards. The influence of sample pH changes on carboxylic acids determination has been tested.
