Abstract
Diphenyldichlorosilane (DPDSCI), a unique reactive chlorosilane with two phenyl groups, was selected to coat the zeolite. The surface characterization results revealed that the modification was successful and the inner structure of zeolite maintained its porosity. Hydrocarbon adsorption tests presented good toluene adsorption performance even under cold temperatures. Regeneration experiments indicated this modified zeolite could be used multiple times without a significant reduction in adsorption efficiency. The Langmuir adsorption isotherm fitted toluene adsorption well and the process occurred spontaneously. Based on this performance, this modified zeolite was found suitable for future application for groundwater remediation in cold regions.
