The optimized conditions for anions were as follows: 0.6 mmol L−1 KOH for 0–14 min, 0.6–15 mmol L−1 KOH 14–20 min, 15–38 mmol L−1 KOH during 20–32 min and finally returned to 0.6 mmol L−1 for a period of 3 min, thereafter the eluent flow rate was 0.38 mL min−1. Similarly, for cations, isocratic elution was adjusted to 0.36 mL min−1 at 17.5 mmol L−1 H2SO4. LOD ranged 3.0–130 pg m−3 and LOQ was within 10–400 pg m−3 (Li+ and PO43−, respectively) as well as recoveries ranged 89% (Ca2+) to 120% (Li+). Major ions were successfully determined in real PM1 and PM2.5 samples. The method used here was found to be a comprehensive, simple, cheap and reliable procedure for studying ions in particulate matter (PM) samples even those from remote areas or near ecosystem natural conditions.Submitted by Edileide Reis (leyde-landy@hotmail.com) on 2014-05-06T14:54:36Z No. of bitstreams: 1 José S.S.
