%X The paper presents flowing injection chemilumines-cence analysis of trace chromium in soil. The method is rapid, sensitive and accurate after the samples are dissolved with mixed acid in a closed teflon vessel under pressure. Most of common ions do" not interfere with the determination of chromium, and interference from cobalt may be eliminated by addition of PAN masking agent in solution of pH 4. The detection limit of trivalent chromium is 6.2×10-13g/ml.The relative standard deviation is less than 3%(n=3 or 4). The recovery rate is 94.3-105.7%.
