The recovery and separation of plutonium(IV) and americium(III) by solid-phase extraction (SPE) on alkylated silica gel S16 modified with N-benzoylphenylhydroxylamine (BPHA) and with its derivatives was studied. BPHA was modified by introducing into the p-position of the phenyl ring of electronactive substituents that differ in their hydrophobicity: CH3, Ph, Cl, F, and NO2. The SPE of plutonium(IV) and americium(III) was studied in the range of acidities from pH 8 to 1 M HNO3. The recovery and separation of these elements was shown to depend on the nature of the substituent, aqueous acidity, and the preparation of S16 to SPE experiments.

Arylhydroxamates are provided having the structure STR1 wherein R1 is hydrogen, lower alkyl, aryl, lower alkenyl, cycloalkenyl, aralkyl, or STR2 wherein n is 1 to 4 and X is hydroxy, alkoxy, amino, C1 -C4 -alkylamino or C1 -C4 -dialkylamino. R2 is hydrogen or lower alkyl; and R3 is C1 -C20 alkyl or C3 -C20 alkenyl, aryl, aryl-alkyl, cycloalkyl, aryl-alkenyl, lower alkoxy, lower alkenyloxy, aryl-alkoxy or cycloalkyloxy. These compound are useful as inhibitors of Δ5 -lipoxygenase and as such are useful as antiallergy agents.
