Abstract

•A novel fast and simple method for simultaneous determination of many elements in dolomite and magnesia has been proposed.•ICP-AES method with slurry sample introduction has been used.•Standard, unmodified ICP-AES apparatus has been employed.•Accuracy has been proved by CRMs analysis.

The slurry nebulization ICP-AES method for simultaneous determination of selected elements in dolomite and magnesia was proposed. Based on the investigation results the optimal conditions for this analysis were as follows: particle size < 40 μm, the nitric acid concentration 10%, the RF power 1.0 kW, aqueous solutions (no dispersing agents) and mixing on magnetic stirrer, during the sample introduction into plasma, as homogenization method. The certified reference materials Dolomite CRM 782-1 and High Purity Magnesia BCS-CRM 389/1 were analyzed. Student's t-test proved that there were no statistically significant differences between determined values and the certified ones. This proves that the slurry sample introduction into plasma in ICP-AES technique can be applied for simultaneous determination of elements in dolomite and magnesia.
