| 内容記述 | A highly sensitive and simple analytical method is applied to the determination of 23 Cs in estuarine and coastal waters. This analytical method combines adsorption of Cs 24 on ammonium 12-molybdophosphate (AMP) and an ion exchange resin column, 25 followed by subsequent ICPMS measurement. Significantly, the method requires a 26 relatively small amount of sample volume (minimum volume: 20 mL) for the analysis by the selection of AMP with a low Cs impurity (0.02 ng-Cs mg-127 -AMP). The method has a detection limit of 1.0 ng L-1 and a limit of quantification of 3.3 ng L-1 28 based on 29 replicate analyses of purified water samples. A sample storage strategy is also 30 investigated: no time dependent changes are found in the concentrations for acidified 31 samples (pH 1.0-1.5) used immediately (storage: 0 days) to those stored for two months in a dark place at room temperature (4-20 oC) or in a freezer (ca. -20 o32 C). Respective Cs concentrations of 95.8+/-0.9, 202.8+/-3.6 and 197.0+/-1.9 ng L-1 33 are 34 obtained in estuarine water (SLEW-3), coastal seawater (CASS-4) and seawater 35 (NASS-5) certified reference materials for heavy metals. In an application of the 36 method to determination of Cs in estuarine and coastal regions of Japan, the obtained Cs concentrations vary from 11.2 to 306.4 ng L-1 37 at a salinity range of 0.1 to 33.6. |
