摘要
采用超声波快速溶样法对干煤棒、沤化煤中腐植酸钠进行抽提.结果显示此方法使制样时间由原来2h缩短至不足20 min,结果误差在允许范围.方法简便、快速,是一种准确可靠提高分析效率的检测分析方法.
Abstract
Sodium humate in dry coal rods and digested coal is extracted using ultrasonic rapid dissolution method.This analysis method not only short-ens the sampling time from 2 h to less than 20 min,which the error is within the allowable range,but also is simple and fast.It is an accurate and reli-able detection and analysis method that improves analysis efficiency.
