Resulting the extraction technology of artificial culturing biofilms, the hydroxylamine hydrochloride (NH_2OHHCl) was selected to extract manganese oxides, and sodium dithionite (Na_2S_2O_4) was used to separate manganese oxides and iron oxides.

用选定的最佳条件对不同时间和地点采集的生物膜进行萃取，发现对目的组分的萃取率可达70.8%~94.6%，而对非目的组分的影响很小(3.3%~11.0%)，满足萃取分离的要求。

Optimum extraction conditions were selected by the condition experiments and the concentration of Cu, Pb, Zn in main components were also determined for revealing the distribution of the heavy metals in the suspended particulate matters. It was found that hydroxylamine hydrochloride (0.006 mol/L NH2OH·HCl+0.01 mol/L HNO3) can remove most of Mn oxides, and sodium dithionite 0.8 mol/L Na2S2O4

结果表明，0.006 mol/L NH2OH·HCl+0.01 mol/L HNO3萃取30 min可以单独萃取悬浮颗粒物中大部分的锰氧化物，0.8 mol/L Na2S2O4（pH=6.0）萃取40 min可以同时萃取铁、锰氧化物，而对非目的组分的影响较小；悬浮颗粒物对Cu、Pb、Zn重金属有明显的富集作用，其中Cu主要结合在悬浮颗粒物的有机质组分中，Pb主要富集在铁、锰氧化物中，锰氧化物和有机质对Zn的分布起主要的富集作用。
