Degradation of Toluene Under the Action of Plant

Chlorophytum Phnom Penh and ivy were used to degrade various concentration of toluene and then the toluene content was detected by gas chromatography.The experiments show that the two plant species can degrade the toluene to some extent and the degradation capability will decrease with increasing the toluene content.Within the same period,the degradation rate of lower concentration(20 mg/m3)of toluene is higher than that of higher concentration(160 mg/m3).After 16 hours of reaction with chlorophytum Phnom Penh or ivy,the degradation rates of toluene(20 mg/m3)are 45.6% and 49.3%,respectively;however,the same values for toluene(160 mg/m3)are only 28.4% and 21.6%,respectively.
