Fig. 13From: A study on the dissolution rates of K-Cr(VI)-jarosites: kinetic analysis and implicationsPlot of the reaction rate constants (kexp) vs. the inverse of the particle’s initial diameter for both reaction media. a Progressive conversion period; b induction period. The results confirm that the unreacted core model satisfactorily describes the dissolution of KFe3[(SO4)2 − X(CrO4)X](OH)6 Back to article page
