ABSTRACT:

This investigation reports the dissolution kinetics of Na-As, K-As and NH4-As jarosites in a sufuric acid medium. The effects of pH, Temperature, particle size, and structure substituents (especially in the M and Z positions of the general formula of jarosite-type compunds, MFe3(ZO4)(OH)6) were investigated.
