摘　　要：介绍了能量色散X荧光分析方法在含水Fe样品测量中的应用。用ANTG 2000型海底X荧光探测系统对含Fe为10%～60%的Fe样进行测量,建立水分对Fe元素特征Kα射线影响的校正模型。结果表明,通过该模型校正,对含饱和水情况下Fe样品的分析相对误差小于4%,具有良好的分析效果。EDXRF applied in measuring water contained samples. During the experiment, the Fe content contained in the sample rangs from 10% to 60% , with ANTG - 2000 X - ray fluorescence analyzer for different Fe - content samples of water inherent, establishing the calibration model for water absorption and scattering on the fluorescence. By the correction model, Fe - content relative error is better than 4% in case of water - saturated samples, with a favorable analyzing ability.
