Scope
Main technical content: The soil and sediment samples are thermally digested with an alkali extraction solution, and trivalent chromium is suppressed by magnesium chloride to obtain a solution containing only hexavalent chromium. Then, the chromium in the solution is determined by inductively coupled plasma emission spectrometry, and the hexavalent chromium content in the soil and sediment samples is calculated
