建立了电感耦合等离子体原子发射光谱法(ICP-AES)测定高碳铬铁中钛量的分析方法。样品采用氢氧化钠和硝酸铵熔融,用硫酸浸出熔融物,在368.520或323.452nm波长下测定钛。进行了溶样试验、分析谱线选择实验、共存元素干扰及校正试验、检出限试验、回收率试验及精密度试验。研究表明:本方法钛检出限为0.01μg/mL,加标回收率为98.3%~100.6%,相对标准偏差(RSD,n=10)为5.7%。应用谱线干扰校正程序可校正共存元素的干扰。 A method for the determination of titanium in high-carbon ferrochromium by inductively coupled plasma atomic emission spectrometry (ICP-AES) was established. The sample was melted with sodium hydroxide and ammonium nitrate, the melt was leached with sulfuric acid and the titanium was measured at a wavelength of 368.520 or 323.452 nm. The sample test was conducted to analyze the spectral line selection experiment, coexisting element interference and calibration test, detection limit test, recovery test and precision test. The results showed that the detection limit of titanium in this method was 0.01 μg / mL, the recoveries were 98.3% ~ 100.6%, and the relative standard deviation (RSD, n = 10) was 5.7%. Applying a spectral interference correction procedure corrects the interference of coexisting elements.
