Abstract: | A method for the preconcentration of the total chromium based on coprecipitation with cerium (IV) hydroxide is proposed for determination of chromium by flame atomic absorption spectrometry. Different factors including carrier element amount, pH, sample volume and matrix ion effects for the precipitation were examined. The detection limit of the total chromium (k=3, N=5) was 0.18 µl-1. The presented method was applied or the determination of chromium in the wastewater samples from Kayseri and Nigde Organized Industrial Region-Turkey and in drinking water from our laboratory, Kayseri with satisfactory results (relative standard deviations below 8%, recoveries 95%). The analytical results obtained by the proposed method for certified copper sample was in good agreement with the certified value. © Springer Science+Business Media B.V. 2007. | URI: | https://hdl.handle.net/11499/7225 https://doi.org/10.1007/s10661-007-9754-7 |
