Abstract

An important issue to consider when determining the chemical composition of slag wool (CCSW) is sample digestion due to the complexity of the matrix. Some methods usually employed to determine the composition of silicate rocks and minerals have been adapted to determine CCSW. However, the dissolution characteristics between rock/glass and slag wool fibers are rather different and thus affect quantitative analysis. The present work reports a reliable, quantitative, low-cost method for the determination of CCSW based on sample fusion, acid dissolution, and subsequent analysis by flame atomic absorption spectrometry. Some oxides were analyzed by gravimetry, allowing the overall chemical characterization of slag wool. Scanning electron microscopy/energy dispersive X-ray spectrometry and traditional current methods were performed for comparison. A study regarding the effects of sample amount and particle size is presented. The results show that the proposed method allows determining CCSW with accuracy; in addition, it offers the advantage of reducing both the melting temperature and the sample preparation time, representing a lower-cost analytical method for the determination of CCSW.

一种低成本测定渣羊毛定量化学成分的方法

当确定渣羊毛（CCSW）的化学成分时，要考虑的一个重要问题是由于基质的复杂性而导致的样品消化。通常用于测定硅酸盐岩石和矿物组成的一些方法已被用于测定CCSW。但岩/玻璃纤维与渣棉纤维的溶解特性存在较大差异，影响了定量分析。本研究报告了一种可靠、定量、低成本的测定CCSW的方法，该方法基于样品融合、酸溶和随后的火焰原子吸收光谱分析。用重量法分析了部分氧化物，对渣羊毛进行了全面的化学表征。扫描电镜/能量色散x射线光谱法与传统电流法进行比较。研究了试样量和颗粒大小的影响。结果表明，该方法可以准确地确定CCSW；此外，它还具有降低熔化温度和样品制备时间的优点，是一种成本较低的测定CCSW的分析方法。
