摘要
本文建立了矿石中物相胶态锡的测定方法。通过对仪器工作条件的实验确立了最佳工作参数,该方法采用(1+3)硫酸加热溶解样品,在7.5%的硫酸介质中,用钇作内标,用电感耦合等离子体发射光谱法(ICP—OES)测定矿石中的物相胶态锡。实验结果表明该方法的相对标准偏差(RSD n=11)≤0.95%,检出限为0.02μg/mL,测定结果比较理想。结论是该方法简便,快速,准确,检出限低,适用于大批量测定矿石中的物相胶态锡。.
A determination method of colloidal tin in minerals was established.This method established the best operating parameters by working conditions of the experimental apparatus.The method used（1＋3） sulfuric acid to heat for dissolving sample.In 7.5%sulfuric acid medium,the yttrium was used as an internal standard,and power inductively coupled plasma emission spectrometry（ICP-OES） was applied to determine colloidal tin in minerals.The results showed that RSD（n=11） was≤0.95%,the detection limit is 0.02μg/mL,more satisfactory results.The conclusion is that the method is simple,rapid,accurate,the lower detection limit,and applicable to analysis of large quantities of colloidal tin ore.
