摘要
文章建立了重量法测定草酸铌中铌量的方法。通过采用正交试验优化了测定的工艺参数,将草酸铌灼烧成五氧化二铌,通过质量的减少测定草酸铌中铌量。该方法的相对标准偏差小于0.4%,通过与不同方法的结果对照,方法的准确度和精密度良好,操作简便快速,易于掌握,完全能够满足生产工艺的需要。
A method has studied to determine niobium of niobium oxalate. The technological parameters have been optimized by orthogonal experiment. Niobium oxalate is burned to niobium pentoxide. Niobium content of niobium oxalate is determined by loss of mass. The method RSD is less than 0.4%. It shows good accuracy and exactitude compared with other methods. The method is very quick and easy tooperate. It satisfies demand of production technology.
