摘要
峨嵋玄武岩同生流体包裹体在800℃爆裂后,2.0g/LNH4Cl溶液提取流体中Pt、Pd,C-410树脂富集-电感耦合等离子体质谱测定,方法相对误差小于25%。激光拉曼光谱与四级质谱测定包裹体的气液成分结果表明:流体中存在一定量的有机组分,这对Pt、Pd以有机螯合态形式进入流体提供了可能。
Bursting the fluid inclusions in Emei basalt samples at 800 ℃, platinum and palladium were leached by 2 g/L NH_(4)Cl and adsorbed by C- 410 anion exchange resin. After desorption from resin the platinum and palladium were measured by ICP-MS. Relative error of this method is less than 25%. The results of gas-liquid composition in fluid inclusions from laser Laman spectrometry and quadrupole mass spectrometer showed that there were some organic components in fluid inclusions. It is possible for platinum and palladium to enter fluid inclusions as the form of organic-chelated states.
