微波加热干燥法测定二水合氯化钡中钡的含量

A study on determining content of barium in barium chloride dehydrate with microwave drying method

为了解决传统重量分析方法费时费电的问题,采用微波加热技术代替传统的灼烧方法,对二水合氯化钡中钡含量进行了测定。确定了微波加热样品至恒量的实验条件为:功率700W,一次放入5个样本,加热13min。用F检验和t检验比较两种方法的测定结果,结果表明没有显著性差异。该方法具有快速、省电、操作简单等特点。

A new method was found for determining microwave drying method instead of traditional ignition content of barium in barium chloride dehydrate with method in order to solve the problem of time-eosing and high power consumption. The experimental conditions has been determined i. e. , the power is 700 W; five samples are put in once; it takes 13 minutes. The results of the two methods were compared by F test and t test. The results show that there is no obvious difference between them. This method has the advantages of fast, energy-saving, easy to operate, etc.
