Carbonating process in sodium aluminate solution has been studied by in-situFTIR spectroscopy. Oscillation phenomenon and nonreproducibility have been observed in IRspectra.

The effects of long fatty acid collector on the structure of sodium aluminate solution was studied with plastics sheets attached water as the background of infrared spectrum.

A solvent flotation-gas chromatography for the determination of sodium stearate in sodium aluminate solution in aluminium hydroxide production by the bayer process was studied.
