摘要/Abstract

摘要：

通过室内试验模拟煤层气产出水中高浓度Cl^-（1000 mg·L^-1）和HCO₃^-（2000 mg·L^-1）对活性氧化铝吸附F^-的热力学影响，并借助扫描电镜（SEM）分析活性氧化铝吸附F^-前后表面性质变化，探讨高浓度Cl^-和HCO₃^-对活性氧化铝吸附F^-的影响.结果表明，活性氧化铝对F^-的吸附反应属于吸热反应（ΔH>0），可自发进行（ΔG<0），熵驱动（ΔS>0）是吸附的主要推动力；当水中高浓度Cl^-和HCO₃^-共存时，并不影响活性氧化铝对F^-吸附反应的方向，但使吸附反应进行不彻底，吸附量降低.

Abstract:

We investigated thermodynamics effect of Cl^- (1000 mg·L^-1) and HCO₃^- (2000 mg·L^-1) in coalbed methane co-produced water on adsorption of fluoride (F^-) by activated alumina, and discussed the change in adsorption capacity by analyzing the surface solid characterizations of activated alumina. The results show that adsorption process is an endothermic reaction (ΔH>0) and entropy (ΔS>0) is the main driving force. The co-existence of high-concentration Cl^- and HCO₃^- will decrease the equilibrium F^- adsorption by activated alumina.

Key words: CBM co-produced water, Cl^- and HCO₃^-ion, F^-, activated alumina, thermodynamics
