Study of the Purification Effect of Two Submerged Macrophytes on the Dimethoate in Water

By cultivating submerged macrophytes in artificial nutrient solution with dimethoate,this paper studied the purification effect of Myriophyllum spicatum and Ceratophyllum demersum on the dimethoate in water. The results showed that: under the same experimental conditions,the purification effect of Myriophyllum spicatum on dimethoate was more stable than that of Ceratophyllum demersum,and the removal rate of Myriophyllum spicatum was also higher. Thus,to get better purification effect on organophosphorus pesticide,the Myriophyllum spicatum and Ceratophyllum demersum can be cultivated jointly.
