Abstract: In this study, the greenhouse water culture simulation experiment was conducted to study the removal effect of bisphenol A from 2 landscape wetland plants of Iris pseudacorus and Canna indica. The residual bisphenol A in the solution and the content of bisphenol A in the roots and leaves in different periods were determined by HPLC-MS. The results showed that I. pseudacorus and C. indica significantly promoted the removal of bisphenol A in water (P<0.05). Compared with the control, the degradation half-life (T_1/2) of bisphenol A in the solution was shortened by 2.70 and 2.11 days, respectively, after planting I. pseudacorus and C. indica. On the 3^rd day of treatment, the removal rate of bisphenol A by I. pseudacorus and C. indica was increased by 57% and 47%, respectively, and on the 5^th day, it was increased by 42% and 30%. On the 5^th day of treatment, 80%~90% of the initial bisphenol A was removed. Further studies by removing the kinetic equation revealed that 99% of the bisphenol A in the treatment of the cultivation of I. pseudacorus and C. indica was removed on the 8^th and 12^th days of the test. The residue dynamics analysis of bisphenol A in plants showed that on the 5^th day, the quality of bisphenol A in the roots of I. pseudacorus was 25 times that in the leaves, and the quality of bisphenol A in C. indica leaves was 90 times that in the roots. The plant extracting ability of I. pseudacorus was significantly stronger than that of C. indica and the ability of I. pseudacorus to transfer bisphenol A from root to leaf was weaker than C. indica.
