Physical and chemical methods of quartz sand

2021-5-3 · The main chemical methods of quartz sand purification are acid leaching and complexation. The acid leaching method is based on the fact that quartz is insoluble in acid (except HF) and other impurity minerals can be dissolved in acid solution, thus further purification of quartz can be realized.

Abstract. A procedure for purification of extracellular glucose oxidase (GO, EC 1.1.3.4) from a filtrate of culture liquid (CLF) of the fungus Penicillium funiculosum 46.1 has been developed using alluvial quartz sand as an adsorbent. Modifying the sand by changing the charge and polarity did not lead to a significant increase in its adsorption capacity towards GO.
