标准加入法定值高钛渣中V₂O₅含量的研究

Study on the Content of V₂O₅ in High Titanium Slag Using Standard Addition Method

本研究是针对经电炉熔炼后高钛渣中杂质分析等问题,进行了用标准加入法定出高钛渣标准中的V2O5的值。目前,国内高钛渣及V2O5等杂质标准,但高钛渣标准中无V2O5的标准,高钛渣中V2O5一直无法用XRF及ICP进行测定。现通过做了大量的样品分析,确定了标准样品中的V2O5的值,从而对未知样(即高钛渣)进行测定V2O5的值,应用到XRF及ICP新建曲线中。结果准确,可以满足生产需要。

This research aimed at impurity analysis of high titanium slag after smelting by electric furnace, and used standard addition method to measure V2O5 value in high titanium slag. At present, in domestic impurity standards of high titanium slag and V2O5, there is no V2O5 standard in high tita-nium slag standard, and V2O5 value in high titanium slag cannot be measured by XRF and ICP all the time. By analyzing a large number of samples, V2O5 value in standard samples was determined, so that V2O5 value in unknown samples (i.e., high titanium slag) was measured, applying to the new curve of XRF and ICP. The results are accurate and can meet the production requirement.
