稀土施用下绿萝对水中磷的净化作用及在线监测研究

Removal of Phosphorus from Water by Scindapsus Aureus with Addition of Rare Earth and Online Monitoring Research

在实验室水培条件下,研究了稀土铈对绿萝净化水中磷的影响。利用在线监测仪实时测定水体的总磷含量变化。对比研究发现,绿萝对磷具有良好富集能力,微量的稀土元素铈能够更好地促进其对磷的吸收,达到净化水体的功能。

Effects of the rare earth element cerium on removal of phosphorus from water by scindapsus au- reus were studied under the hydroponic condition in a laboratory. An on-line monitor was used to conduct the real-time detection of the variation of the total phosphorus contents in water body. The comparative study showed that Scindapsus aureus has good accumulation ability of phosphorus and trace amounts of Ce is able to promote the absorption of phosphorus which result in purification of water body.
