摘要: 采用低压聚乙烯镶边垫底的粉末样品压片制样，用ARL ADVANT’XP＋型X射线荧光光谱仪对土壤和水系沉积物样品中C、N、Na2O、MgO、Al2O3、SiO2、P、S、Cl、K2O、CaO、Sc、Ti、V、Cr、Mn、Fe、Co、Ni、Cu、Zn、Ga、Nb、Zr、Y、Sr、Rb、Pb、Th、Ba、As、Br、Hf、La、Ce和Nd等36个组分进行测定。重点研究了C、N等元素的测定务件和痕量元素的背景选择和谱线重叠校正问题。使用经验系数法和康普敦散射作内标校正基体效应。经标准物质校验，结果与标准值吻合。Abstract: A method for the determination of C,N,Na_(2)O,MgO,Al_(2)O_(3),SiO_(2),P,S,Cl,K_(2)O,CaO,Sc,Ti,V,Cr,Mn,Fe,Co,Ni,Cu,Zn,Ga,Nb,Zr,Y,Sr,Rb,Pb,Th,Ba,As,Br,Hf,La,Ce and Nd in soil and stream sediment samples by X-ray fluroescence spectrometry with pressed power
