“…A wide range of researchers have carried out experiments to synthesize jarosite under laboratory conditions (synthetic jarosite) where the principal characteristics employed during the synthesis were high synthesis temperatures (>90 • C) and time (>24 h) [5][6][7][8]. For example, alkaline decomposition of jarosite-type compounds obtained with synthesis temperatures between 93 and 98 • C and time of~24 h has been executed, where the particle sizes were from 20 to 80 µm in diameter [8,17,19,22,23]. Additionally, synthesis of jarosite particles with diameters <50 nm has been reported, however, the presence of other agents such as potassium fluoride, δ-MnO 2 nanosheets, and other variables were necessary during the synthesis in addition to the traditional wet chemical method [17,24,25].…”

“…Synthesis of potassium jarosite employed in this work was similar to the method reported by Dutrizac and Kaiman [33], and Salinas et al [19] with considerable modifications. And were prepared modifying the method used as well as all chemicals, Iron (III) sulfate, Fe2(SO4)3 and potassium sulfate, K2SO4, as source of potassium jarosite; sodium hydroxide, NaOH and sulfuric acid, H2SO4, were utilized for adjusting pH in this work and were purchased from Sigma Aldrich with high purity (> 99 %).…”

“…Wide range of researchers carried out experiments to synthesize jarosite under laboratory conditions (synthetic jarosite) where the principal characteristics employed during the synthesis were high synthesis temperatures (> 363 K) and time (> 24 h) [2][3][4][5]. For example, alkaline decomposition of the jarosite type-compounds obtained with the synthesis temperatures between 366 and 371 K and time ̴ 24 h was executed, where the obtained particles sized where from 20 to 80 µm in diameter [13,[19][20][21][22]. Additionally, synthesis of jarosite particles with very small diameters, close to nanometric values, were reported but with the disadvantage that it is necessary the presence of other agents such as potassium fluoride, δ-MnO2 nanosheets and other variables in addition to the traditional wet chemical synthesis method [14,23,24].…”
