采用菲咯嗪法对黄渤海沿岸部分地点2009年表层水样以及山东荣成湾内的天鹅湖、近岸和远海部分站点2009~2011年采集的表层水样进行了Fe含量的测定,此外还检测了天津、荣成及日照采集的地下水水样。结果显示渤海沿岸除河北秦皇岛东山浴场,营口、秦皇岛西浴场、天津、东营支脉河口和昌邑沿岸表层水样的Fe(Ⅲ)以及Fe(t)浓度明显高于山东省黄海沿岸,而黄渤海沿岸各水样中Fe(Ⅱ)浓度均较低且差异不明显。荣成湾近岸和远海以及其内的天鹅湖站点水样的Fe(Ⅱ)、Fe(Ⅲ)和Fe(t)浓度周年变化不明显,Fe(t)浓度总体上为天鹅湖>近岸>远海。地下水中Fe(Ⅲ)浓度高于Fe(Ⅱ),但一些地下水中Fe(Ⅱ)浓度仍处于较高水平。
Phenanthroline method was used to determine the Fe content of surface water samples collected from surface waters of 2009 along the Yellow Sea and Bohai Sea coasts in 2009 and surface water samples collected from 2009 to 2011 of Swan Lake, near shore and distant sea sites in Rongcheng Bay, Shandong Province. In addition, Tianjin, Rongcheng and sunshine collected groundwater samples. The results show that the concentrations of Fe (Ⅲ) and Fe (t) in the surface water samples of the coasts of the Bohai Sea are obviously higher than those of the Yellow Sea in Shandong Province, except the Dongshan Bathing Pool of Qinhuangdao in Hebei Province, the surface water samples in Yingkou, Qinhuangdao West Bathing Beach, Tianjin, Dongying Branch Veins and Changyi coasts, The concentration of Fe (Ⅱ) in the water samples along the coast was lower and the difference was not obvious. The annual changes of Fe (Ⅱ), Fe (Ⅲ) and Fe (t) concentrations in water samples from Rongcheng Bay in the near and far sea and within the Swan Lake were not obvious. The concentrations of Fe (t) Far sea. The concentration of Fe (Ⅲ) in groundwater is higher than Fe (Ⅱ), but the concentration of Fe (Ⅱ) in some groundwater is still at a high level.
