摘要: 研究了水芹莱(Oenanthejavanica)对黄金废水中全的净化与富集作用。在静态试验中,废水量15L,植物量为0.262kg,金的起始浓度为0.5、1.0和2.0mg·L-1,污水停留时间为5d其净化率分别为98.9%、99.2%和97.2%,而在根部灰分中金的富集量则分别为3027.2、8835.1和12164.6g·t-1

关键词: 黄金废水, 水芹菜, 净化, 富集

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.
