微细粒褐煤中腐植酸的水溶特性及其影响研究OA北大核心CSTPCD
Water-Soluble Characteristics and the Effects of Humic Acids on Micron-Sized Lignite
为了充分利用褐煤,采用光学显微镜、FTIR、接触角、Zeta电位等分析技术,重点研究褐煤腐植酸在水中随浸泡温度的溶解特性以及其溶解前后的褐煤总酸基含量、表面亲疏水性和表面荷电等变化规律.结果表明,随着浸泡时间的延长,浸泡温度的升高,褐煤腐植酸的溶解量增大;在浸泡温度50℃,浸泡时间2h时,腐植酸溶解量达15.636 mg/L;随着溶解温度的升高,褐煤中含氧官能团减少,其中总酸基由2.768 mmol/g降到2.431 mmol/g,接触角由100…查看全部>>
In order to make use of lignite,the dissolution of HA in lignite with the change of soaking temperature,and the content of total acid group,hydrophilieity and charge of lignite surface after dissolution was investigated.The result showed that the capacity of dissolution of HA in lignited increased with the increase of soaking time and temperature.When soaking temperature was 50 ℃,soaking time 2 h,the capacity of HA was 15.636 mg/L.The analysis of FTIR was us…查看全部>>
