摘　　要：本研究探究了黏土矿物(即蒙脱土和高岭土)崔化邻苯二酚生成挥发性有机物呋喃的过程受不同环境因子的影响,包括不同pH值(5~9)、不同酸根离子(硝酸根离子、草酸根离子)、不同有机质(腐殖酸和富里酸)以及不同光照条件。实验结果表明,黏土矿物能够显著催化邻苯二酚的非生物转化,生成呋喃。在pH值为5~9的范围内,pH值越高越有利于呋喃的生成。硝酸根离子、腐殖酸和富里酸对于该反应影响不大,而草酸根离子可以促进呋喃的生成。增加光照能够显著促进粘土矿物催化邻苯二酚生成呋喃的反应速率。本研究结果为解释土壤中小分子有机物的非生物转化提供了依据。This study investigated the process of clay minerals(i.e.montmorillonite and kaolin)transforming catechol into volatile organic compound of furan,which is influenced by different environmental factors,including pH(5~9),inorganic acids(nitrate ion,oxalate ion),organic matters(humic acid,fulvic acid),and the light condition.The experimental results indicate that clay minerals can significantly catalyze the transformation of catechol with the generation of furan.Within the pH range of 5~9,the higher pH condition produced more furan.Nitrate ion,humic acid,and fulvic acid showed limited impact on this reaction.While,oxalate ion significantly promoted the formation of furan.In addition,the reaction was greatly enhanced under the light condition.The results of this study improve our understanding about the abiotic transformation of small molecule organic matter in soil.
