【摘要】 建立了中和滴定法测定铝灰渣和除尘灰中氮的方法，通过实验确定了铝灰渣和除尘灰分析样品的加工粒度、称样量、蒸馏过程、滴定过程等相关参数，用于铝灰渣和除尘灰样品的测定，测定的相对标准偏差为0.74%、0.36%，加标回收率98%以上。更多还原

【Abstract】 A neutralization titration method was established for the determination of nitrogen in aluminum ash and dust removal ash.The processing particle size, sample weight, distillation process, titration process and other related parameters of aluminum ash and dust removal ash samples were determined through experiments. The relative standard deviations of the determination were 0.74%and 0.36%, and the recovery rate of spiking was above 98%.更多还原
