传统的重量分析资料并无以无水硫酸铁作为称量物形式的记载。一般均借助于约1000℃的高温灼烧手段,使铁的硝酸盐或硫酸盐转变成为三氧化二铁称量物形式而进行定量分析。我们经试验发现,在一定条件下,无水硫酸铁可以作为称量物形式应用于工业分析。据资料记载,硫酸铁常形成一系列水合物,经加热可得无水盐,温度超过480℃时无水硫酸铁即
Traditional gravimetric data do not contain anhydrous ferric sulfate as a weighing material. In general, a quantitative analysis is carried out by means of high-temperature burning at about 1000 ° C to convert iron nitrate or sulfate to the form of ferric oxide. We have found through experiments that under certain conditions, anhydrous ferric sulfate can be used as a weighing material in industrial analysis. According to the data records, often form a series of hydrated ferric sulfate, available by heating anhydrous salt, the temperature exceeds 480 ℃ anhydrous ferric sulfate that
