Alkaline Reactivity of Arsenical Natrojarosite

Jarosites são compostos que podem sofrer substituições com vários elementos de importância ambiental (tais como As) durante a precipitação. Arsênico integrado na estrutura poderia influenciar a solubilidade da jarosita, potencialmente estabilizando a estrutura em uma ampla gama de condições que são toleradas pela jarosita pura. A reatividade álcali é caracterizada pela remoção de íons sulfato e...
