本文采用无火焰原子吸收分光光度法测定海水不同形态的铬。研究表明:山东半岛南部近海颗粒铬对总铬的比率在60%以上,是铬存在的主要形态;六价铬对总铬比率低于3%,是最次要的形态;三价铬对总溶解铬的比率在80%以上,所以三价铬在溶解态中占主要形态。铬在该海域的分布特征是:丁字湾口为高值区,崂山湾为低值区。 - In this paper, non-flame atomic absorption spectrophotometric determination of different forms of seawater chromium. The results show that the ratio of chromium to total chromium in the offshore Shandong Peninsula is more than 60%, which is the main form of chromium. The ratio of hexavalent chromium to total chromium is less than 3% The ratio of dissolved chromium is above 80%, so the trivalent chromium occupies the main form in the dissolved state. Chromium in the distribution of the sea are: T-bay mouth high value area, Laoshan Bay low value area. -
