摘　　要：利用石墨炉原子吸收光谱法测定海水中铬,塞曼效应扣除背景,选择抗坏血酸为基体改进剂。线性范围5—15μg/L,相关系数为0.9999,回收率为90%—102%,相对标准偏差为7.0%。The total chromium in seawater was determined by AAS with graphite furnace, vitamin C as a matrix modifier and Zeeman effect for the elimination of background. The linear range is from 5μg/L to 15μg/L with a recovery of 90--102% ,linear relation coefficient of 0. 9999 and RSD of 7. 0%.
