Comment: |
trace of 2:1 phyllosilicate contaminants; extractions with NaOH, NH2OH*HCl, dithionate-citrate-bicarbonate solutions showed that residual allophanic and Fe-oxide impurities were present, although the presence of octahedrally bound Fe3+ in the Al layer of kaolinite cannot be totally dismissed; also in [ZCSA88] |
