چکیده
Here we report the results of a study on active surface species pristine and modified (Li-Na) 2 CO 3 eutectic using in situ Raman spectroscopy technique. The effects gas compositions, temperature, time, alkaline earth have been systematically studied. 4 2– , HCO – C O 5 are identified as three major by combined theoretical density functional theory calculations. further reveal that preferably formed presence H O, high concentration. With addition Ba to eutectic, /HCO shifts become more pronounced.

متن کاملIn situ analysis of dynamic laminar flow extraction using surface-enhanced Raman spectroscopy
In this study, we performed micro-scale dynamic laminar flow extraction and site-specific in situ chloride concentration measurements. Surface-enhanced Raman spectroscopy was utilized to investigate the diffusion process of chloride ions from an oil phase to a water phase under laminar flow. In contrast to common logic, we used SERS intensity gradients of Rhodamine 6G to quantitatively calculat...
