Fig. 14From: A study on the dissolution rates of K-Cr(VI)-jarosites: kinetic analysis and implicationsDissolution curves for S1–S7; a [H3O+]/[OH−] = 0.1 mol L−1, T = 50 and 30 °C respectively, d0 = 44–38 µm. b Comparison of the calculated rate constants vs. CrO4 2− proportion in the structure of potassium jarosite. Results show that the incorporation of the chromate ion does not modify the dissolution rateBack to article page
