摘要:

通过能量色散X 荧光衍射仪(EDXRF)对3种南海潮间带海绵: 细薄星芒海绵Stelletta tenui (Lindgren)、澳大利亚厚皮海绵Craniella australiensis (Car ter) 和多皱软海绵Halichondria hugosa (Ridley & Dendy) 的元素组成和含量进行了研究, 并与两种黄海潮间带海绵进行了比较。结果表明, 海绵体内的元素组成受种属差异的影响较大, 溴元素的含量可能同一定的活性物质产生相关。另外, 不同海绵具有骨针形态的多样性, 为深入研究内部合成机制提供了材料。

Using EDXRF to test elemental compositions of marine intertidal sponges

李斌,靳艳,张卫

Abstract:

The inorganic elemental compositions of three kinds of marine sponges Stelletta tenui (Lindgren) , Craniella australiensis (Carter) and Halichondria hugosa (Ridley & Dendy) in the intertidal zone in the South China Sea are given by energy-dispersive X-ray fluorescence spectrometry (EDXRF). The elemental compositions vary largely among different sponge species. Comparing the data of the Yellow Sea with that of the three studied sponges in the South China Sea, we conclude that the sponge with a lower bromine content may produce bioactive bromine metabolites. Two kinds of sponges with similar content of spicule have different appearances, which will show different catalytic mechanisms of spicule formation. All of these will be helpful to the research of metabolism of sponge.

Key words: sponge element EDXRF
