Abstract: This research aimed to remove toluene vapor contaminated in the ambient environment by Epipremnum aureum (Lind. and Andre) bunting. About 5 L of glass chamber were set to close experiment system. The leaf area index of the experimental plant was approximately 150 cm2. Initial toluene concentrations were examined separately; 0.87, 1.73, 3.46, 6.92, 10.38, 13.84 and 17.30 mg L-1. The results showed that the concentration equilibrium time rise within 120 min. The equilibrium concentrations were 0.33, 0.45, 0.90 1.80, 2.70, 3.60 and 4.50 mg L-1 and the removal capacity of toluene absorption of the leaves were 13.60, 32.00, 45.80, 107.30, 182.00, 235.10 and 295.10 μg cm-2, respectively. The toluene removal efficiency of almost initial concentrations was equal on average 74% indicating that the amount of toluene absorptions greatly depended on the amount of the initial toluene concentrations.
