摘要：The Sr-isotope ratios of several samples from a natural and an agricultural soil from Ravenna were determined using aqua regia and the two-step sequential extraction. Results indicate that the two-step extraction can provide the researcher with wider and more precise information on Sr sources, thus being a more suitable methodology for achieving scientific goals than the aqua regia extraction. Lastly, the extracts of hydrochloric acid and aqua regia display similar ranges of δ 87 Sr, indicating that the two procedures provide comparable information on Sr sources.
