An efficient method combining thermal annealing and acid

This process enables to attract impurities to the surface of silica grains where they can be easily extracted by partial dissolution in an acid mixture. Thus obtained silica was investigated by inductively coupled plasma atomic emission spectrometry (ICP– AES) method. Major impurities present in silica sand were Al, K, Fe, Na, Ca, Mg and B.Get more +
