摘要
试验了罗丹宁螯合纤维直接在酸性介质中分离富集Ａｇ的性能及其应用。结果表明，该纤维具有快速富集Ａｇ，易解脱，耐强酸，成本低，寿命长等优点。用于地质样品中Ａｇ的分离富集，结果满意。
A new chelate resin has been studied for the enrichment of Ag in geological samples by FIA-on line. The resin can be directly used to seperate and enrich Ag from the matrix,even from strong acidic solution and be used repeatly for a long time.Ag can be easily eluted with warm thiourea. For 30 seconds enrichment, the determination limit of Ag is 0.0005μg/ml, RSD = 0.94% (Ag= 0.008μg/ml).
