Kinetics of extraction of nitric acid into binary mixture of tri-n-butyl phosphate and normal paraffin hydrocarbon

Micro-Raman Technology to Interrogate Two-Phase Extraction on a Microfluidic Device

“…The adduct is formed via a hydrogen-bonded bridge between the phosphoryl group on TBP and the HNO 3 proton. The adduct forms at or close to the interface before transferring to the organic phase . The extraction can be measured by determining the concentration of HNO 3 in the organic and aqueous phase as a function of time.…”

“…The adduct forms at or close to the interface before transferring to the organic phase. 29 The extraction can be measured by determining the concentration of HNO 3 in the organic and aqueous phase as a function of time. Concentrations of HNO 3 and TBP in n-dodecane were chosen to reflect concentrations relevant to the PUREX process.…”

Selective Separation of HNO 3 and HCl by Extraction: The Investigation on the Noncovalent Interaction between Extractants and Acids by Density Functional Theory

“…Data from several studies suggest that HNO 3 and HCl mostly generate 1:1 adducts with the extractant. ,,− Moreover, it is emphasized that the calculation ignores the participation of water molecules to simplify the model. For the purpose of reflecting the solvent environment in real extraction processes, the solvation model based on density (SMD) , was adopted in calculations.…”

Online Monitoring of Solutions Within Microfluidic Chips: Simultaneous Raman and UV–Vis Absorption Spectroscopies

“…This paper extends our group’s efforts in the design, development, and demonstration of spectroscopic-based applications on chemical systems in hazardous and harsh environments. Sensor applications are tailored for use in nuclear fuel reprocessing − solutions containing lanthanides, actinides, and transition metal and related nuclear waste solutions, − at macro- , and microfluidic − scales.…”
