The organic molecules which make up coal are held together not only by covalent bonds, but also by a substantial network of hydrogen bonds as well as certain other weak intermolecular associations, which together are called the secondary structure. It is believed that acidic hydroxyl groups are res

Acidic functional groups in five low-rank coals from various parts of the world have been determined by aqueous ion exchange and non-aqueous titration procedures. The total acidity found by titration was, in general, significantly higher than that obtained by ion exchange at pH 13 for all the coals.

Victorian brown coals from Loy Yang, Yallourn and Yallourn North Extension open cut mines were studied. When these coals are used as ion exchange materials, their ionic selectivities follow the Irving-Williams order for metals from the first transition metal series, i.e. Mn < Co < Ni Zn. The cation
