Among various types of wet chemical analyses, titrimetric methods are one of the most classical methods used to measure FeO values. Although titrimetric methods yield accurate FeO values, it is time consuming. Much progress has been made on measuring FeO using analytical instruments; this includes new methods such ion chromatography (Kanai, 1990; le Roex and Watkins, 1995), Mössbauer spectroscopy (Lalonde et al., 1998), phenanthroline spectrophotometry (Husler et al., 2011; Tarafder and Thakur, 2013), X-ray absorption near-edge structure (XANES) spectroscopy (Farges, 2001; Ohta et al., 2006; O’Neill et al., 2006, 2018; Berry et al., 2010, 2018; Cottrell and Kelley, 2011; Zhang et al., 2018), and electron probe microanalysis (EPMA) (Hughes et al., 2018; Li et al., 2019). In each of these developments, it is crucial to compare the results of unknown geological samples with geochemical reference materials; therefore, the importance of geochemical reference materials with certified values is increasing. The certified values of geochemical reference materials have previously been determined mainly by a titrimetric method. During this method, samples are first decomposed by sulphuric acid (H2SO4) and hydrofluoric acid (HF) in crucibles. They are then titrated with a potassium dichromate (K2Cr2O7) solution to allow volumetric calculation of the amounts of FeO.

日本地球化学学会版权所有©2020。通过与标准物质的测量值进行比较,验证了数值。在各种湿化学分析方法中,滴定法是测量FeO值最经典的方法之一。虽然滴定法能得到准确的FeO值,但耗时长。利用分析仪器测量FeO已取得很大进展;这包括离子色谱等新方法(Kanai, 1990;le Roex和Watkins, 1995), Mössbauer光谱学(Lalonde等人,1998),菲罗啉分光光度法(Husler等人,2011;Tarafder and Thakur, 2013), x射线吸收近边缘结构(XANES)光谱学(Farges, 2001;Ohta等人,2006;O’neill et al., 2006, 2018;Berry等人,2010,2018;Cottrell and Kelley, 2011;Zhang et al., 2018)和电子探针微分析(EPMA) (Hughes et al., 2018;Li等人,2019)。在每一个发展中,将未知地质样品的结果与地球化学参考物质进行比较是至关重要的;因此,具有认证值的地球化学标准物质的重要性日益增加。地球化学标准物质的检定值以前主要是用滴定法测定的。在该方法中,样品首先在坩埚中被硫酸(H2SO4)和氢氟酸(HF)分解。然后用重铬酸钾(K2Cr2O7)溶液滴定,以计算FeO的体积。优化普拉特滴定法测定地球化学标准物质中FeO的方法是一个难点
