SIMPLE METHOD FOR ANALYSIS OF HEXAVALENT CHROMIUM

摘要

PURPOSE: A simplified method for analyzing chrome(VI) is provided to determine the existence of the chrome(VI) in a target specimen with a color developing reagent coloring by the reaction of the chrome(VI). CONSTITUTION: A simplified method for analyzing chrome(VI) is as follows. A target specimen is inserted into a solvent which the chrome(VI) can be dissolved so that the chrome(VI) is eluted from the target object to the solvent(S110). The target specimen in which the chrome(VI) is eluted is removed from the solvent so that the rest is obtained(S120). A color developing reagent which colors a specific color by reacting to the chrome(VI) is inserted into the rest(S130). The existence of coloring by the color developing reagent is checked whether the chrome(VI) is contained in the target specimen or not is determined(S140).
