Emanation thermal analysis of TIXOTON (activated bentonite) treated with organic compounds

摘要

TIXOTON (Ca-bentonite activated by sodium carbonate) was treated with four different organic compounds representing organic aids, bases, non-ionic polar molecules and non-polar molecules found in waste and sewage water. They were acetic acid, diethylamine, ethylenglycol and n-heptane. The first three were used as 5/100 aqueous soltuions, and the latter as a neat liquid. Cation exchange reactions, which occurred between the montmorillonite fraction of TIXOTON and acetic acid or diethylamine solutions, resulted in H-Al-montmorillonite or diethylammonium-montmorillonite, respectively.
