Journal Title: Chinese Journal of Inorganic Analytical Chemistry - Year 2025, Vol 15, Issue 6
Abstract
Zircon sand is a type of mineral that is challenging to decompose，and elements such as Zr，Ti，Hf are prone to hydrolysis. Accurate analysis of the element content in the zircon sand processing process sample holds a guiding significance for the mining and evaluation of zircon ore resources. The optimal pretreatment method was chosen，which involves using sodium carbonate-boric acid melting and diluent hydrochloric acid-tartaric acid solution for microthermal extraction. The experimental conditions of flux dosage，melting time，and temperature were optimized. An analytical method for the determination of Zr，Ti，Hf，Fe，Mn，Sn，Ba，and Al in the zircon sand processing process sample was established by means of inductively coupled plasma atomic emission spectrometry (ICP-AES). The matrix matching method was adopted to overcome the matrix interference during the testing process. Zr 339.198 nm，Ti 336.121 nm，Hf 277.336 nm，Fe 259.940 nm，Mn 257.610 nm，Sn 189.989 nm，Ba 233.527 nm，and Al 396.152 nm were selected as the analytical spectral lines. The experimental results revealed that the correlation coefficient of each element calibration curve ranges from 0.999 3 to 0.999 9，the method detection limit varies from 0.000 8 to 0.011 μg/g，and the lower limit of determination was from 0.003 to 0.034 μg/g. In accordance with the experimental method，the accuracy and precision experiments of Zr，Ti，Hf，Fe，Mn，Sn，Ba，and Al in GBW07156 and GBW07157 were determined，and it was concluded that the relative standard deviation (RSD，n=9) was 0.56%-3.4% and the addition recovery rate was 95.0%-104%. Zircon sand processing process samples were analyzed simultaneously，and the relative standard deviation (RSD，n=9) was 0.94%-3.2%，with the addition recovery rate ranging from 95.0% to 105%. Compared with other determination methods，it is demonstrated that this method can achieve accurate analysis of Zr，Ti，Hf，Fe，Mn，Sn，Ba，and Al and offers a theoretical foundation for evaluating the zircon sand processing process.
