灵山岛海域铬的形态
黄华瑞1, 庞学忠1
中国科学院海洋研究所
摘要:
在灵山岛海域测定了Cr(Ⅵ)、Cr(Ⅲ)、Cr(S)、Cr(P)和Cr(T)。研究表明,四季中Cr(T)与Cr(P)以春季含量最高,这与浮游生物有一定的相关性。Cr(P)在春、冬季为铬的主要存在形态,尤以春季含量最高,而夏季较低。Cr(Ⅲ)在夏、秋季为主要形态。在四季中Cr(Ⅵ)含量较低,均为次要形态。而Cr(Ⅲ)在溶解态中则为最主要形态。Cr(Ⅲ)/Cr(T)与Cr(P)/Cr(T)呈较好的负相关,不同形态铬存在着转移过程。

CHROMIUM SPECIES IN LINGSHANDAO REGION
Abstract:
Cr(Ⅵ), Cr(Ⅲ), Cr(S), Cr(P) and Cr(T) in Lingshan Dao region have been determined by flameless atomic absorption spectrophotometry. Investigation indicated that contents of Cr(T) and Cr(P) in the spring are high in all seasons, Cr(P) is main speciation in the spring and winter, especially in spring. Its content is lower in the summer. Cr(Ⅲ) the summer and autumn is the principal speciation. Cr(Ⅵ) is of secondary speciation in all seasons. Cr(Ⅲ) is the dominant speciation. Cr(Ⅲ)/Cr(T) and Cr(P)/Cr(T) possess a fairly negative relation.
