Distribution and Correlation of P and Fe Fractions in Sediments of Typical Urban Shallow Lakes
典型城市浅水湖泊沉积物中磷与铁的形态分布及相关关系

The fractions of phosphorus(P) and Fe in the surface sediments of three typical urban shallow lakes(Xuanwu Lake,Daming Lake and Mouchou Lake) were determined using improved methods of SEDEX and BCR,respectively,and the relationship between P and Fe in sediments was also analyzed.P analyses showed that the relative lower content of Al-P was found in sediments of three urban lakes,while the percentage of Fe-P was in the range of 17.10%-27.88%,16.68%-27.06% and 0.06%-0.17%,respectively,in Xuanwu Lake,Daming La...
