【摘要】 采用作者研究的OP- 乳化剂增敏姜黄素分光光度法测定海水中的溶解硼,用ICP- AES法测定海水中的溶解锶。发现在杭州湾海水盐度5 .563 ~26 .397 ,氯度3.022 ~14 .582 范围内,硼浓度为0 .68 ~3.24mg/kg,锶浓度为1 .29~5 .88mg/kg,B(mg/kg)/Cl 比值为0 .219~0 .245,平均值为0.232±0 .007 ,Sr(mg/kg)/Cl 比值范围为0.398 ~0.440 ,平均值为0.417 ±0.011 。结果表明,湾内海水中的硼和锶浓度与海水盐度或氯度均有很好的线性正相关关系,丰水期与枯水期水样数据关系相同,不因采水时间不同而变化。实验数据统计回归线与理论稀释线比较后表明,湾内海水中锶与硼均具有良好保守性质;湾内海水中的硼和锶主要来自湾外潮汐输入。湾东北沿岸海水高的B/Cl比值,暗示着此处有含硼工业废水排入湾内,认为B/Cl 比可作为近岸河口海水硼污染的一种指标。杭州湾海水中未检测到硼有机络合物。

【Abstract】 Dissolved boron in the seawater of the Hangzhou Bay has been determined with sensitized reaction of emulsor the OP micelle curcumin method newly developed by us, and dissolved Sr in seawater has been determined with the ICP AES method. Boron in seawater of the Hangzhou Bay varies from 0.68 to 3.24mg/kg in chlorinity(Cl) ranging 3.022 to 14.582 and Sr varies from 1.29 to 5.88mg/kg. The B or Sr content shows a high linear correlation with Cl or S (salinyity) for seawater samples of the flood season as well as the dry season. The ratios of B(mg/kg) to Cl are between 0.219~0.245, and with a mean value of 0.2315 ±0.007. The Sr(mg/kg)/Cl ratios are between 0.398~ 0.440 and with a mean value of 0.417±0.011. Boron and Sr are found to be conservative in the seawater of the Hangzhou Bay. The B and Sr in the Hangzhou Bay are derived mainly from the external seawater through tidal currents. In the northeast coastal region of the Hangzhou Bay hign values of B/Cl are observed which could be due to received boron containing industrial waste water. It seems that B/Cl is useful in finding out borate pollution in estuaries.
