  • 摘要: 本文建立了一种快速测定模拟固硫剂或灰渣中硫含量的方法.线性响应范围为:1%—30%.测定相对误差在±10%之内.采用本法可一次测定样品中硫的各种形态的含量. 本文还建立了一种新的制样方法——涂膜法.较之常规的压片法,需要样品量只有十分之一.同时,改进了测量精度,扩大了测量范围.使利用X射线荧光法测定低含量硫(0.1%)成为可能.
    Abstract: A method of quick determination of sulfur content in simulated sulfur sor-bents or coal ash was established.Its linear response range is 0.1-30%.Furthermore, it can simutaneously determine the concentrations of different valences of sulfur in the sorbents.A new method of sample preparation by membrane coating, which needs only one tenth of sample required by conventional pressing tablet method.The range of determination can be expanded to 0.001%.This method has been used for the determination of sulfur in actual Sorben-ts and coal ash with satisfactory results.
