At the solid/liquid interface: FTIR/ATR--the tool of choice.

摘要: For the last 7 years, we have been researching various aspects of Bayer process. Predominant among these has surface chemistry process solids. To this end, using Fourier transform infrared (FTIR) attenuated total reflection (ATR) spectroscopy for in situ studies surfaces solids sodium oxalate and aluminium trihydroxide under extreme (high ionic strength, high pH), Bayer-like conditions. FTIR/ATR is one few techniques currently available to scientists wishing explore solid/liquid interfacial phenomena situ. Using investigative technique, information regarding nature adsorbed species can be readily acquired, with details concerning adsorbate orientation adsorption/desorption equilibria, speciation, mechanisms kinetics obtainable. Not surprisingly, become tools choice those interface, body literature on subject steadily growing over 10-15 years. This review addresses current state knowledge area respect spectroscopy, as well introducing some more fundamental theoretical practical technique. Particular emphasis placed upon applied research. In writing review, draw a considerable amount expertise use (in particular, considerations involved), large comprehensive database focussing primarily investigation processes
