| 摘 要： | 为科学评价磷在河道沉积物中的环境行为,在模拟条件下研究了上海市进木港和苏州河沉积物中磷的分布形态、吸附特征及释放规律.结果表明:(1)2种沉积物中碎屑钙磷(De-P)浓度最高,闭蓄态磷(Oc-P)次之,其他形态磷浓度相对较低,而活性磷中以铁磷(Fe-P)为主；(2)2种沉积物对磷的吸附均符合线性方程,在4.0h时基本达... |

| Abstract: | In order to scientifically evaluate the environmental behavior of phosphate in urban channel sediments,the distribution,adsorption and releasing law of phosphate in Jinmu Harbor sediment and Suzhou River sediments of Shanghai were studied.The conclusions were as follows:(1) The content of De-P and Oc-P were highest in two sediments,other species were less,and the Fe-P had most content among labile phosphate;(2) The adsorption isotherms of phosphate all accorded with linear equation in two sediments and achi... |
