An indirect, sensitive and accurate method for the determination of trace amounts of hydrazine is described. In this proposed the spectrophotometric method is based on its reduction properties of hydrazine with a known concentration of potassium permanganate to reduce the colour. The absorbance of unreduced permanganate is measured the colour difference at different wavelengths 546 and 526 nm which show an absorption spectrum with hydrazine. Hydrazine can be determined in the range of 100 - 700 µg/ml with correlation coefficient of 0.999 and relative standard deviation 1%. The method is successfully applied for the determination of hydrazine in water streams in nuclear reactors/purex process/boiler water and polluted water samples

“…Among these methods, Raman spectroscopy and UV-Vis absorbance are the most relevant analytical techniques to measure actinide concentrations in aqueous solutions. Absorption spectroscopy is widely used for the analysis of actinides in the nuclear industry, especially for uranium 4,[6][7][8] and plutonium, [9][10][11][12] which are the main elements involved in the plutonium, uranium, reduction, and extraction (Purex) process. These two actinides have the advantage of having f-f electronic transitions, which give characteristic absorption bands in the visible and near infrared, allowing direct quantification without prior treatment.…”

Microfluidic In-Situ Spectrophotometric Approaches to Tackle Actinides Analysis in Multiple Oxidation States

The study and development of present and future processes for the treatment/recycling of spent nuclear fuels require many steps, from design in the laboratory to setting up on an industrial scale. In all of these steps, analysis and instrumentation are key points. For scientific reasons (small-scale studies, control of phenomena, etc.) but also with regard to minimizing costs, risks, and waste, such developments are increasingly carried out on milli- or microfluidic devices. The logic is the same for the chemical analyses associated with their follow-up and interpretation. Due to this, over the last few years, opto–microfluidic analysis devices adapted to the monitoring of different processes (dissolution, liquid–liquid extraction, precipitation, etc.) have been increasingly designed and developed. In this work, we prove that photonic lab-on-a-chip (PhLoC) technology is fully suitable for all actinides concentration monitoring along the plutonium uranium refining extraction (plutonium, uranium, reduction, extraction, or Purex) process. Several PhLoC microfluidic platforms were specifically designed and used in different nuclear research and development (R&D) laboratories, to tackle actinides analysis in multiple oxidation states even in mixtures. The detection limits reached (tens of µmol·L−1) are fully compliant with on-line process monitoring, whereas a range of analyzable concentrations of three orders of magnitude can be covered with less than 150 µL of analyte. Finally, this work confirms the possibility and the potential of coupling Raman and ultraviolet–visible (UV–Vis) spectroscopies at the microfluidic scale, opening the perspective of measuring very complex mixtures.

“…Determination of uranium in environment is of importance. At present, a number of methods have been proposed for the determination of uranium, including titration methods [1][2][3], catalytic beacon sensor [4], colorimetric sensors [5], inductively coupled plasma-mass spectrometry [6], atomic emission spectrometry [7], surface-enhanced Raman spectroscopy [8] and spectrophotometry [9]. Although each of these methods has its own advantages, there are also some disadvantages in these methods.…”
