| 摘 要： | 通过事先对有机碳含量较高的样品于1000℃ 下灼烧2 h,计算其烧失量,再将灼烧后的样品经Li2 B4 O7(67％)和LiBO2(33％)的混合熔剂熔融制样后,经X射线荧光光谱仪测定,能够有效地去除因有机质含量高导致的分析结果的偏差,总体的平均相对误差从11.1％ 减少到了4.5％,而且较湿法化学分析节省时间.分析结...

| Abstract: | By burning the sample 2 hours with a high organic carbon at 1000℃in advance to calculate the loss on ignition,and then melting the burned sample with Li2B4O7(67%)and LiBO2(33%)solvent to prepare the sample and measuring it with X-ray fluorescence spectrometer,it can remove the analysis results deviations caused by high organic matter content effectively,the overall average relative error was reduced from 11.1%to 4.5%and it can save time compared to wet chemical analysis.The analysis results of this method deviate from the results of wet chemical analysis very little,and the accuracy is improved greatly compared with the direct tablet analysis. |
