摘要
Dieffenbachia picta, Acrostichum aureum, Ficus religiosa, Lagerstroemia macrocarpa, Alstonia scholaris, and Dracaena sanderiana leaf materials have high benzene removal efficiency. So, these six plant leaf materials were investigated for continuous adsorption systems. In adsorption systems, A. aureum and A. scholaris leaf materials were found to have the highest benzene removal capacity. Physical sorption was confirmed by hexane desorption and Fourier transform infrared spectrometry (FT-IR). Pseudomonas putida immobilized on A. aureum and A. scholaris leaf cassava-beads were used as biofilters. A total of 1.2-1.5 min with an enrichment medium was shown to be the suitable retention time and suitable nutrients for the biofilter system.
