天然闪锌矿/铁闪锌矿中铁和锌含量及分布的多方法确定(英文)
发布时间:2023-04-19 04:44
采用化学滴定和光谱技术(便携式X射线荧光光谱(P-XRF)、电子探针能量色散光谱(EPMA-EDS)、电子探针波长色散光谱(EPMA-WDS)和飞行时间二次离子质谱(To F-SIMS))测定天然闪锌矿样品中Fe和Zn的含量。此外,利用EPMA-WDS成像和To F-SIMS成像分析闪锌矿样品中Fe和Zn的分布。结果表明,各光谱法测定的Fe和Zn含量与化学滴定法测定的Fe和Zn含量具有良好的线性关系(R2>0.77),并且总体上Fe的R2值大于Zn的R2值。成像分析结果表明,Fe和Zn在闪锌矿中分布不均匀。
