摘要
以微量滴定法测定粉煤灰中铁的含量,相对标准偏差小于5%并与常量法进行对比,结果两种方法无显著性差异,t检验和F检验均在允许范围之内,微量滴定精密度高于常量方法.
The concentration of iron in powder coal cinder determined by micro - titration, The RSD is lower than 5 %. The parallel determination results were compared with those obtained from the conventional buret. The t- test value and F - test value are in the allowed range.
