挥发性有机物在活性炭中的吸附构效关系
Structure-property relationship of volatile organic compound adsorption in activated carbon
摘要
Abstract
A slit-pore model of activated carbon was selected to investigate the adsorption behavior of molecules in different types of volatile organic compounds(VOCs)in pores with varying sizes by adopting the molecular simulation method.The structure-property relationship between activated carbon and VOCs molecules was explored via the genetic algorithm.Experimental results show that under ambient pressure,the adsorption amount is the lowest in pores with pore size of 1 nm and reaches its maximum in 3 nm pores.Before VOCs achieve adsorption equilibrium,the pores with a smaller size in activated carbon preferentially serve as adsorption sites.A structure-property relationship model for VOCs adsorption on activated carbon was built.The cross-validation results show that this model has high accuracy and enables rapid and precise evaluation of activated carbon's VOCs adsorption performance,providing valuable guidance for the rapid development of novel adsorption processes of activated carbon.关键词
