摘　　要：本文采用模拟土壤基体的方法人工制备测定用标准样品,应用回归分析求取经验系数校正基体效应,建立了测定土壤总硫量的X射线荧光光谱分析方法。该法简便快速、灵敏(最低检出限小于5μg/g)。测定结果与化学法基本一致。A method for determining the total sulfur in soils (organic matter content less than 25%) by XRF is described. That is rapid, simple and sensitive (L. L. D. less than 5μg/g of sulfur). Standard soil samples used in determining is artifical by adding standard sulfate solution to simulated soil mineral. The matrix effects are corrected by experience coefficients from regression analysis. Results by this method agreed well with the values from chemical method.
