微波加热快速测定腐植酸总量

Rapid Determination of the Total Content of the Humic Acid in Coal Samples by Using

利用微波加热技术，在密闭容器内通过压力浸提、消解试样，能大大加快分析速度。本实验测定了不同煤样中的腐植酸总量，讨论了功率、时间、酸度等因素对分析结果的影响，并与标准方法相对照。用ｔ－检验法及Ｆ－检验法检验，没有明显差异，结果令人满意。该法具有省时、省力、经济、不污染环境、宜于批量分析、便于普及推广等优点。

Using microwave-heating method, coal samples were digested with sodium pyrophoshatesodium hydroxide and were dispelled with potassium bichromate-sulfuric acid in the closed vessel.This paper has discussed the effect of analysis result by power, time and acidity etc.In different coal sample, humic acid amount was measured. Compared with classical method, Using t-test and F-test the result is satisfactory. This method has many advantages such as saving time, saving labour, saving money and not polluting environment.This method is appropriate for batch analysis and easy to spread.
