菊花新品系对气态复合苯—甲苯去除效果测试

Performance-Testing in Removing Benzene-Toluene Binary Gas Using New Lines of Chrysanthemum

采用动态熏蒸方式,选取更为接近实际环境的复合污染模式,在国内首次对菊花新品系进行苯-甲苯去除效果测试。结果表明:品系间对苯或甲苯的去除效果差异显著。虽然所测试的大多数菊花新品系对甲苯的去除效果更好,但是9个菊花新品系对苯和甲苯没有表现出明显的选择性去除机制。熏蒸6 h,品系2、4、5、9对苯和甲苯的去除率都在30%以上,而品系7对甲苯的去除率由熏蒸3 h的13%降至熏蒸6 h的0。从累计去除量的角度考虑,品系2、4、5、8、9对苯-甲苯的去除效果较好,可考虑做进一步的实际环境应用测试。

It was the first performance-testing in China to remove gaseous benzene-toluene using new lines of Chrysanthemum morifolium in the dynamic fumigation.The results showed that while selective removal of benzene or toluene was not significantly shown in nine lines of Chrysanthemum,most of them removed more toluene than benzene.Removing rates varied significantly among lines.Samples from 6-hour of fumigation suggested that above 30% of removal rate of both benzene and toluene were reached by lines of the number 2,4,5,9,in the meanwhile removal rate of toluene from line of the number 7 dropped to 0 from 13% at 3-hour of fumigation.From the results of removal amount,lines of the number 2,4,5,8,9 should be taken for application performance testing in real world considering better performance-testing results.
