Abstract

In this paper, the degradation of simulated mixed organics commonly found in nuclear waste streams was studied under a combined influence of sonication and magnetic field. Nanoscale bimetallic iron-nickel was used as source of Fenton reaction. The data were fitted to obey second order kinetics. The extent of degradation followed the trend: TBP-EDTA-citric acid greater than TBP-EDTA, greater than TBP alone. The influence of the three variables that govern degradation behaviour viz. sonication energy, magnetic field and time were evaluated with response surface methodology. The model could predict the ratio of total organic carbon content to a maximum error of only ∼6%.
