Application of X-ray fluorescence spectrometry in composition analysis of metal oxides

传统光谱法对船舶金属氧化物成分检测产生的紧密度波动,会影响其检测精密度。为了有效解决这一问题,设计在传统射线荧光光谱法的基础上,引入二元比例分析法,提出新型光谱检测方法。根据金属氧化物基础理论和朗格斯比尔液体检测准则,确定光谱吸光度,引入L,K两元曲线,完成光谱参数调试,制备检测样本试剂和溶剂,混合后进行充分氧化反应,填入硝酸氨、氢氨和高纯氨气,以间隔增温的形式完成样本试剂的氧化消解,最后根据样本检出限确定样本吸光度值,结合二元比例检测公式,获取最大吸光度下检测目标的元素量,该元素量即为最后成分分析结果。实验数据表明,二元比例射线荧光光谱分析法的元素光影曲线校准度提高了29%,增强效应影响因子降低了21%,可以有效提高船舶金属氧化物检测分析的精密度。
