“…(23) W i ndscal e investigators (I8' 22) studied a number of possible types of primary and secondary products and concluded t h a t hydroxamic acids were an important, though certainly n o t the only, complexing group while a1 1 primary products tested were passive. The complexing a b i l i t y of hydroxamic acids i s known (34,35,36,37) and t h e i r presence in degraded solvent has been demonstrated.

Normal waste processing a t the Hanford operations requires the use of many organic materials, chiefly in the form of complexing agents and diluents. These organic materials and t h e i r chemical and radiolytic degradation products, have potential f o r complexing f i s s i o n products and transuranium elements, both in the waste streams and upon i n f i l t r a t i o n into s o i l , perhaps influencing future sorption or migration of the nuclides.--Particular complexation characteristics of various nuclides which cons t i t u t e the major fission products, long-lived isotopes, and the most mobile 1 in radioactive wastes a r e discussed briefly with regards t o t h e i r anticipated sorption or mobility in s o i l s . Included in the discussion a r e Am,

“…Thermal behavior studies of complex compounds have been extended by application to Cu(II) DL-a-alaninate monohydrate (1), the Pd complexes of a number of thiols (35), a series of metal benzohydroxamates (227), and a series of metal-amine complexes (58). In the last investigation (58), the thermal stability of Cu(II), Ni(II), Co(II), Mn(II) and Zn(II) complexes were found to follow their solution stability.…”

“…Hydroxamic acids and their derivatives have been known as metal chelating compounds for more than a half century. The compounds were applied for organometal synthesis, spectroscopic analysis and metal extraction [ 6 – 15 ]. Chiarizia et al studied the extraction kinetics of iron(III) at biphasic medium [ 16 ].…”

Liquid-liquid iron(III) extraction was investigated using benzyl fatty hydroxamic acids (BFHAs) and methyl fatty hydroxamic acids (MFHAs) as chelating agents through the formation of iron(III) methyl fatty hydroxamate (Fe-MFHs) or iron(III) benzyl fatty hydroxamate (Fe-BFHs) in the organic phase. The results obtained under optimized conditions, showed that the chelating agents in hexane extract iron(III) at pH 1.9 were realized effectively with a high percentage of extraction (97.2% and 98.1% for MFHAs and BFHAs, respectively). The presence of a large amount of Mg(II), Ni(II), Al(III), Mn(II) and Co(II) ions did affect the iron(III) extraction. Finally stripping studies for recovering iron(III) from organic phase (Fe-MFHs or Fe-BFHs dissolved in hexane) were carried out at various concentrations of HCl, HNO3 and H2SO4. The results showed that the desired acid for recovery of iron(III) was 5 M HCl and quantitative recovery of iron(III) was achieved from Fe(III)-MFHs and Fe(III)-BFHs solutions in hexane containing 5 mg/L of Fe(III).
