| 摘 要： | 应用SMT法对崇明村镇级河道沉积物中的磷形态进行了分析,揭示了沉积物中磷的形态分布及潜在转化趋势。结果表明,沉积物中的磷主要以无机磷(IP)的形态存在,占总磷(TP)的85%以上,有机磷(OP)的含量较低,仅为9.93%～18.45%;而在无机磷中,磷灰石态无机磷(AP)是主要的赋存形态,占IP的70%以上;pH与AP呈极显著正相关,是沉积物理化性质中的重要指标,对磷的潜在环境行为有重要影响。

| Abstract: | The fraction distribution and potential transformation of Phosphorus(P) in sediments of rivers in Chongming’s village were analyzed by dint of SMT method.The results showed that the inorganic phosphorus(IP),accounting for more than 85% of Total P(TP),was the predominant fraction of total phosphorus(TP),while the organic phosphorus(OP) in TP only ranged from 9.93% to 18.45%;while AP was main fractions in IP,over 88%;pH value,of significant positive correlation to AP,would be important indexes on the physical and chemical properties of sediments,which impacted on the potential environmental behavior of P fractions. |
