Experimental studies of alunite I. 18 O- 16 O and D-H

We have determined oxygen and hydrogen isotope fractionation factors between alunite and water over a temperature range of 250-450??C by reacting synthetic natroalunite with 0.7 m K2SO40.1 to 0.65 m H2SO4 solutions to produce K-rich alunite. From 88 to 95% alkali and isotope exchange were observed in most of these experiments, and the partial equilibrium method was used to compute

The visible and infrared spectral properties of jarosite

For the C3v sulfates of jarosite and alunite one ν 1, one ν 2, two ν 3, and two ν 4 vibrations are expected (Adler and Kerr 1965; Hug 1997). Alunite exhibits spectral features due to the vibra-tions of sulfate groups, hydroxyl groups, metal-oxygen bonds and lattice vibrations. Jarosite spectra contain these as well as iron excitational features.
