This study examines the CO2 removal rates of five wetland plants (Cyperus alternifolius, Dracaena fragrans, Iris ensata, Iris setosa and Thalia dealbata) by using saturation reaction and first-order reaction kinetic equations. it was determined that the elevation Of CO2 levels stimulated the plant-CO2 uptake rate. The maximum CO2 removal rates (k) of plants were found to range between 0.76 and 1.21 gm(-2) h(-1). The magnitude of first-order kinetic coefficient of plants (k') had a close relationship with CO2 level at half-velocity (K). For consistency, the same kinetics were applied to the continuous flow experiment. A saturation kinetic approach was well suited to estimate the removal rate of CO2 in continuous flow system, while a first-order kinetic approach was limited to inflow CO2 levels below 500 ppm.
