โœฆ Synopsis


Several investigators

1-3 have used methyl isobutyl kctonc to cstract chromium(V1) from aqueous hydrochloric acid solutions as a separation tcchliirluc bcforc the determination of chromium. However, no data have hecn rcportetl concerning the process by which this extraction takes place. It is the object of thcsc studies to investigate the mechanism of the estraction of chromium(V1) by kctoncs.
