适用范围：This International Standard specifies a method for the determination of polyacrylate (PA) superabsorbent powders in airborne dust by measurement of sodium (Na) by atomic absorption spectrometry (AAS). PA dust samples are collected in polystyrene acrylonitrile air-monitoring cassettes with polytetrafluoroethylene filters and porous plastic backing pads. This method is applicable to the determination of collected superabsorbent powder in the range between 0,2 μg and 60 μg (limit of detection near 0,2 μg) of superabsorbent powders. NOTE This test is designed to determine low levels of sodium and requires that very clean handling conditions be observed. The use of deionized/distilled water containing very low sodium content is critical for successful analysis.
