A number of monohydroxamic acids like salicyl, cinnamo, m-nitro benzo, tartaric and benzohydroxamic acids as well as dihydroxamic acids were synthesized and characterized using spectroscopic techniques with the aim to develop selective chelating agents for determination of transition metals. Optimum conditions for maximum complexation and wavelength for spectrophotometric determination were investigated. lambda(max) of 308 +/- 2 was observed with all ligands investigated, while pH-2 and 11 were found optimum pHs for maximum complexation. Interferences effect of selected cations on determination of vanadium(V) and its detection limits were also investigated.
