The research was performed to study the simultaneous detection of a homologous series of α, ω-dicarboxylic acids (C2–C10), oxalic, malonic, succinic, glutaric, adipic, pimelic, suberic, azelaic, and sebacic acids, with capillary electrophoresis using indirect UV detection.
Good separation efficiency in 2,6-pyridinedicarboxylic acid as background electrolyte modified with myristyl trimethyl ammonium bromide was obtained.
The dicarboxylic acids were ionised and separated within five minutes.
For the study, authentic samples were collected onto dry cellulose membrane filters of a cascade impactor (12 stages) from outdoor spring aerosols in an urban area.
Hot water and ultrasonication extraction methods were used to isolate the acids from membrane filters.
Due to the low concentrations of acids in the aerosols, the extracts were concentrated with solid-phase extraction (SPE) before determination.
The enrichment of the carboxylic acids was between 86 and 134% with sample pretreatment followed by 100-time increase by preparation of the sample to 50 μL.
Inaccuracy was optimised for all the sample processing steps.
The aerosols contained dicarboxylic acids C2–C10.
Then, mostly they contained C2, C5, and C10.
Only one sample contained succinic acid.
In the study, the concentrations of the acids in aerosols were lower than 10 ng/m3.
