Abstract:

Studies over the period January 1990-January 1993 of grant No. DAJA45-90-C-0007 centered principally on investigations of the thermal andor photolytic degradation of toxic compounds in aqueous solutions containing hydrogen peroxide as sacrificial oxidant and FeIII salts as catalytic agents. Extensive investigations were carried out on the simulants 4-NPDEP paraoxon, 4-nitrophenyl diethyl phosphate, 4-NPIPP 4-nitrophenyl isopropyl phenyl phosphinate, DEP diethyl ethyl phosphonate, NOX nitro-o-oxylene, TSPAP thiosulfuric acid-S-2-diisopropyl amino ethyl-O-phenylester, 4-NP 4- nitrophenol, 4-CP 4-Chlorophenol, and DBP diethyl benzylphosponate. Both DBP and KHP potassium hydrogen phthalate were used as model compounds in attempts to elucidate the mechanism of the photocatalytic reaction in presence of FeIII salts.
