“…Because of this importance, a simple, rapid and highly sensitive method for uranium determination is required. Several techniques have been developed for the determination of U(Vl) including a-spectrometry [1], gas chromatography [2], neutron-activation [3], spectrophotometry [4] and pulse polarography [5]. These techniques have various dif®culties often insuf®cient sensitivity and expensive instrumentation.…”

A new method for trace uranium, based on the adsorptive accumulation of the chelate compound formed between U(Vl) and [4-(2-hydroxyethyl)-l-piprazine ethane sulfonic acid] on glassy carbon electrode is described. The optimum conditions for the complex formation were: 0.02 M HClO 4 , pH 4.0, accumulation potential 0.1 V (vs. AgyAgCl), frequency 15 Hz and SW amplitude 25 mV. Under these conditions, it was easy to determine the metal ion in a concentration range as low as 1610 À9 M. The effect of possible interfering metal ions, e.g., Cu(II), Fe(III), Al(III), Mg(II), etc. has been tested. Application of the method for the determination of the metal ion in some industrial samples has been successfully done.

“…Vanadium ions have many structural roles reflected by its structural and electronic analogy to phosphorus [31][32][33][34][35][36][37][38][39] . Vanadium is also an enzyme co-factor 25,27,[38][39][40][41][42][43][44][45][46][47][48] . Vanadium can act and function in the biosphere include investigation in to the fundamental coordination and redox chemistry of the element 49 .…”

The 2,4-Dihydroxy cinnamaldehyde thiosemicarbazide has been synthesized. Complex of 2,4-dihydroxy cinnamaldehyde thiosemicarbazide with transition metals, Vanadium (v) has been synthesized in methanol medium. The formation of the complex are endothermic processes. The ligand was characterized by melting point, elemental analysis, absorption spectra and antimicrobial activity while the complex was chara cterized by melting point, absorption spectra, A simple and sensitive spectrophotometric method was developed for transition metal complex of 2,4-dihydroxy cinnamaldehyde thiosemicarbazide. The optimum condition for complete colour development have been established. The stability constant, dissociation constant & change in free energy of vanadium (v) has been determined by Job's variation & mole ratio method indicate that the M:L is 2:1 . Tolerance limit of diverse ions in the determination of vanadium (v) with is investigated. Antimicrbial activity and antifungal activity have been studied.

“…Uranium(VI) occurs in seawater therefore as an anion, and has a very long residence time of 2±4610 6 years [2]. Several techniques have been developed for the determination of U(VI) in water including a-spectrometry [2], neutron activation analysis [3], spectrophotometry [4], molecular¯uorescence spectroscopy [5], X-ray¯uorescence spectroscopy [6], complexometric titration [7], pulse polarography [8], gas chromatography [9] and quartz crystal microbalance [10]. Most of these techniques are not sensitive enough for the trace determination of U(VI) and some of these also require expensive instrumental set ups.…”

A voltammetric method for the determination of trace level of uranium is described. The method is based on an adsorptive accumulation of the uranium-Mordant red 19 (MR19, 4-[(5-chloro-2-hydroxy-3-sulfo-phenyl)azo]-5-hydroxy-3-methyl-1-phenyl-pyrazole, sodium salt) complex on a hanging mercury drop electrode followed by the reduction of the adsorbed complex. , which corresponds to the cross-sectional area of 154 A Ê 2 /molecule. The effect of various operational parameters on the stripping response is discussed. Also interferences from other metal ions are examined.
