摘要:

A direct and simple method for arsenic in organic compounds involves merely dissolution of the sample in an organic solvent, such as benzene, cyclohexane, or methyl isobutyl ketone, and direct aspiration into a fuel-rich acetylene-oxygen flame. The arsenic line at 2350 Å is used; the detection limit is 2.2 ü/ml. From iron and copper matrices arsenic is isolated by extraction from a solution 9 M in HCI and 0.25 M in KI with benzene.
