Study on the Effect of Indoor Air Quality by Negative Air Ion of Plant

[Objective]The research aimed to study the new channel improving indoor air quality. [Method]Under natural state and the condition of opening negative air ion generator by plant,negative air ion,positive air ion and CI in glass room were studied. [Result]Under natural state,average negative air ion concentration in glass room was 1 084 ion /cm3 and was lower,while average negative air ion concentration under the condition of opening negative air ion generator by plant was 684 190 ion /cm3,which was 631 times of that under natural state. Average positive air ion concentration under natural state was 946 ion /cm3,while average positive air ion concentration under the condition of opening negative air ion generator by plant was 976 ion /cm3. The difference was insignificant( P 0. 05). Seen from CI,the value under the condition of opening negative air ion generator by plant was 685 457. 62,which was 539 730 times of that under natural state. [Conclusion] It could significantly improve indoor air quality by opening negative air ion generator by plant in glass room.
