Abstract: The static experiment showed that after the 15 L waste water with an original concentration of0.5, 1.0 and 2.0mg Au·L-1 and a plant weight of 0.262kg was maintained for 5 days, thepurification rates of god-bechng waste water was 98.9,99.2 and 97.2 %, and the accuznulation amount of gold in the plant was 3027.2,8835.1 and 12164.6g·t-1 root ash, respectively.
