Extraction and purification of quartz in rock using hot ...
Quartz extraction and purification is essential for the successful measurement of 10 Be and 26 Al by AMS for exposure dating. The common procedure involves repetitive etching by ultrasonic heating and agitation in a dilute aqueous HF solution (2% w/w), which has proven adequate for quartz rich rock (i.e., granite, quartzite).We have developed an alternative method using hot phosphoric acid ...
