摘　　要：活性白土在石油炼制、医药、农业等多个行业有着广泛的应用,用酸对白土活化是主要方法之一。以陕北志丹白土为原料,用无机酸对其进行活化,详细研究了活化过程中活化酸的种类、酸浓度、反应时间、反应温度等对活性白土质量的影响。结果表明,志丹白土活化的适宜条件为:盐酸浓度8%,活化温度80℃,活化时间5～6h。The activated clay have been widely used in petroleum,medication,agriculture etc.It is one of primary technique by acid in processing clay ore. The sour kind,the sour concentration,the reacting time and the reacting temperature were studied in processing clay ore.The factors affecting the quality of product were also discussed.The best technical conditions are 8% hydrochloric acid,80 ℃ temperature and 5～6 h reacting time respectirely.
