Constructed wetlands have recently been widely used around the world to purify wastewater. As an important component of constructed wetland system, plants improve water quality by increasing oxygen concentrations in the rhizosphere. However, little was known about the ability of oxygen release from roots with different species. And the reason of the difference is still unclear. This paper investigated the variation of oxygen release rate from roots of Typha and phragmite using a titanium (Ш) citrate buffer. Compared the ability of oxygen release from Typha and phragmite. The results shows that oxygen release rates with the same condition were higher for Phragmites. This difference is caused by the special structure of Phragmites. The aerenchyma of Phragmites is good at the oxygen transport. The results of this paper can help us to choose better vegetation species for wastewater treatment.
