选用4种南方常见水生植物（狐尾藻、轮叶黑藻、金鱼藻和水绵）,以郴州重金属污染土样作为底泥,通过4种藻类单独及两两组合的水培方式,在室内模拟条件下培养1周,培养结束,比较各藻类的生长情况;经过浓盐酸＋浓硝酸＋高氯酸消化处理后,利用原子吸收光谱法测定藻体内铜锌铅3种重金属的含量。结果表明,单独培养和组合培养,藻体均有不同程度的增长,以狐尾藻的长势最好,狐尾藻＋轮叶黑藻的培养中狐尾藻的生长百分比达到最大值65.7%。轮叶黑藻＋水绵的组合方式可用于治理铜污染严重的区域,轮叶黑藻和水绵体内的铜含量可分别达到4.69mg/kg和20.13mg/kg,富集系数分别为0.041和0.178;金鱼藻＋轮叶黑藻的组...

Southern common aquatic plants（Myriophyllum spicata,Hydrilla verticillata,Ceratophyllum demersum and Spirogyra） were used to investigate the accumulation ability of aquatic plants to heavy metals,utilizing the soil sample in Chenzhou as sediment,cultured by combination of two and individually,training for a week in simulating condition.Then,comparison of the growth of various algae,after treated by hydrochloric acid,nitric acid and high chlorine,digested for a night,then determined by atomic absorption spectrometry.Results indicated that eith...
