✦ Synopsis

Abstract

The Goodhue method is adapted to estimate rotenone in concentrations varying between 0.01 and 0.10 mg./c.c. The influence of spray auxiliaries and of dehydrorotenone, the primary decomposition product of rotenone, has been investigated. A method for determination of rotenone in the presence of dehydrorotenone is developed for application to the examination of spray deposits and residues.
