| 摘 要： | Research of chromium speciation in the Bohai Gulf showed that content of particulate chromium in estuarine area rea ched more than 90%, so it is an existing dominant speciation in the Bohai Gulf. Ratio between trivalent chromium to total dissolved chromium is over 80%, whereas contents of hexavalent chromium is very low. The mean content of Cr (Ⅲ) is 5.6 times higher than that of Cr (Ⅵ). Thus trivalent chromium is the prinicipal speciation of valency state of chromium in the Bohai Gulf.Under the physical and chemical condition at the eatuary transferring mechanism of chromium in seawater of Bohai Gulf is done by absorption, complexion and subsequent settlement in the sediments of trivalent chromium by suspended matter. Therefore suspended matter plays a part on the purification of sewater for this gulf.

| Abstract: | Research of chromium speciation in the Bohai Gulf showed that content of particulate chromium in estuarine area rea ched more than 90%, so it is an existing dominant speciation in the Bohai Gulf. Ratio between trivalent chromium to total dissolved chromium is over 80%, whereas contents of hexavalent chromium is very low. The mean content of Cr (Ⅲ) is 5.6 times higher than that of Cr (Ⅵ). Thus trivalent chromium is the prinicipal speciation of valency state of chromium in the Bohai Gulf.
Under the physical and chemical condition at the eatuary transferring mechanism of chromium in seawater of Bohai Gulf is done by absorption, complexion and subsequent settlement in the sediments of trivalent chromium by suspended matter. Therefore suspended matter plays a part on the purification of sewater for this gulf. |
