%X In a kinetic experiment, the absorption of NH4+, NO3- and H2PO4- by three different emergent macrophytes (Canna generalis, Cyperus papyrus, Colocasia tonoimo) in waterlogged condition were analyzed in relation to values of landscape esthetics and economic value. Based on the analysis, the uptake rate of H2PO4- was highest in C. generalis. In fact, C. generalis continued to absorb H2PO4- in even low ion concentration conditions. This suggested that C. generalis successfully coped with a wide range of H2PO4- concentration. On the other hand, the uptake rate of NO3- was highest in C. papyrus. It was, however, not able to successfully adapt to low nutrient conditions (as C. generalis). The highest uptake rate of NH4+ was also in C. papyrus, and even of low concentrations of NH4+. Also, NH4+ absorption was lowest in C. generalis. The application scope of three plants on restoration of polluted water varied with ion absorption characteristics of the plants. C. generalis did generally well in all levels of H2PO4- polluting water. C. papyrus, on the other hand, was only suitable for pre-treatment of seriously NO3- polluting water. Then C. generali was usable in maintaining water quality after improvement to a certain degree. C. papyrus was applicable in various concentrations of NH4+ polluting water. C. generalis grew better in water environments that were less polluted by NH4+.
