九龙江口悬浮颗粒的主要元素化学

The Major-element Chemirtry of Suspended Particles from jiulong River Estuary

本文中讨论九龙江河口海水悬浮颗粒中主要元素的含量分布、结合形态以及颗粒化学组成的主要控制因素。 1986年4月在九龙江河口沿盐度递增方向采集表层海水悬浮颗粒样品。总悬浮物(TSM)、POC的含量测定方法同文献[1]。将悬浮颗粒样品进行0.5

Suspended particles from the surface waters of Jiulong River estuary were collected during April, 1986. Abont 20% of Fe, 87% of Mn, 10% of Ai, 60% of P, Ca, Mg and 35% of Cu were present in the weak acid soluble fraction. The increase of weak acid soluble Fe, Al, Mn, Si Ca and Mg with the salinity gradient demonstrated the occurrence of authigeaic processes. The principal component analysis indicated that terrestrial input is the most important factor controlling the major element composition. The 'authegenic' processes are the secondary important factor, whereas the biological factor is the relatively less important one.
