摘要

Gypsum accounts for sulfate sulfate sulfur and pyrite for pyritic sulfur, are occurring in coal; dissolution of their model samples were carried out using RuCl_3 solution. The extent of soluble calcium from gypsum at 25 deg C and 3.90-6.31% at 80 deg C in the same time period. The rate constants for gypsum dissolution are exceedingly higher (1,12-4.23)10~-3 s~-1, than those observed for pyrite, (1.58-3.92)10~-6s~-1. It is observed that RuCl)3 is a suitable reagent for the removal of gypsum by dissolution process.
