Sedimentation field-flow fractionation-inductively coupled plasma optical emission spectrometry: Size-based elemental speciation of air particulates
The applicability of sedimentation field-flow fractionation-inductively coupled plasma optical emission spectrometry (SdFFF-ICP-OES) was investigated for the elemental size characterization of air particulate matters less than 10 μm (PM10). The effects of various dispersing agents and pH values on t...

The applicability of sedimentation field-flow fractionation-inductively coupled plasma optical emission spectrometry (SdFFF-ICP-OES) was investigated for the elemental size characterization of air particulate matters less than 10 μm (PM10). The effects of various dispersing agents and pH values on the dispersion stability of air particulates were examined by zeta potential measurement. Anionic surfactants, which were 0.1% FL-70® (a powerful alkaline detergent) and 0.1% sodium dodecyl sulfate (SDS), exhibited zeta potential values more negative than -30 mV, suggesting that both surfactants could efficiently disperse air particulates. A 0.1% FL-70 with pH 8 was chosen as both dispersing agent and carrier liquid. The developed SdFFF method provided satisfactory separation efficiency and reproducibility (<3% RSD).
