The many studies performed on the alkaline reaction of bentonite have been directed, obviously, to the montmorillonite alteration.
On the other hand, we have shown that the alkaline reaction of FEBEX bentonite is significantly accelerated with the increase in time and temperature (Ramirez et al.
Once the nature of the alkaline reaction of bentonite had been studied in detail, the rate of montmorillonite transformation was calculated by using the mineralogical quantification of smectite (calibrated by the decrease of the 4.
The particular nature of FEBEX bentonite alkaline reaction products
Recently, a rate-blanking method has been introduced that compensates for absorbance changes of bilirubin and hemoglobin under the strongly alkaline reaction conditions [6, 7].
