Measurement of Chromium in Soil by Atomic Absorption Spectrophotometry

Introduction

The Soil Contamination Countermeasures Law was implemented in Japan in 2003. It prescribes soil elution standards and soil content standards for hexavalent chromium, as well as metals such as cadmium and lead. Although trivalent and hexavalent are typical atomic valencies for chromium, the standard value is prescribed for hexavalent chromium. This Application News introduces an example of chromium analysis on a commercial soil standard sample (JSAC 0401 Brown Forest Soil, manufactured by The Japan Society for Analytical Chemistry).
