| Abstract(E) | In order to investigate the concentrations of organic acids in diesel exhaust during cold-start under low-temperature conditions, organic acids were directly collected from exhaust gas using a sorbent tube. Organic acids concentrations during engine warm-up were obtained by analyzing eluted samples from sorbent material. Since the desorption efficiencies of organic acids from sorbent tubes depends on the sorbent material, and the stability of the organic acids eluted samples depends on storage conditions, the optimal sorbent material and storage conditions were investigated. The sorbent tube using acrylic ester material with phosphoric acid treatment, combined with freezer storage of the eluted samples, showed the highest performance in terms of desorption efficiencies and the storage stability. |
