| Abstract: | Chemical determination method of acidic functional group containing oxygen in coal was improved by ultrasonic treatment along with heating with constant temperature water bath. The conditions of ultrasonic and heating treatment in the process of determination were optimized respectively. The results indicated that ultrasonic treatment and heating with constant temperature water bath improved the reaction of acidic functional group in coal and its derivates and eliminated the distrubance of environmental fac... |
