| 摘 要： | 研究了一个测定花岗岩风化壳中REE存在形态的方法。以0.2 mol/L MgCl_2,2.5 mol/LHCl,0.5 mol/L NaOH及含15%H_2O_2的2.5 mol/L HCl连续提取风化壳试样中的稀土。经X射线衍射、红外光谱及剖面试样测试,论证了每一提取态的内涵,提出了花岗岩风化壳中非原生矿物相稀土存在活性态、铁铝共沉淀态和有机结合态的新认识。

| Abstract: | The determination of REE speciation in weathering crust of granites was researched. TheREE in weathering crust was successively isolated by 0.2mol/L MgCl_2, 2.5mol/L HCl, 0.5mol/L NaOH and 2.5mol/L HCl including 15 percent H_2O_2. The connotation of every specieswas analyzed by means of X-ray diffraction, infrared absorption spectrum and measurementof weathering crust samples. New knowledge that REE exists as active, iron aluminiumcoprecipitation and combination with organic compounds was put forward. |
