55 activated Milos bentonites. According to FTIR data, the smectite mineral in the activated Milos bentonite has much more iron in its octahedral sheets than the two nonactivated bentonites from Milos. The contents of trace elements are presented in table 7-9. Table 7-8. Contents of sulphur, total carbon, carbonate- and non-carbonate carbon as well as H20-. pH was measured in BaCl2-extract, sample to solution ratio 1:50. a, the results are preliminary because the method validation has not yet been completed.
