Water is one of the most stable and abundant complexes on nature that can be polluted with natural and human factors. Therefore, it is necessary to ensure a timely warning for possible accumulation of polluting metal in natural waters in order to protect public health. One of the economic and rapid methods for elements removal is displacement of metals by biosorption. The purpose of this study is to investigate how much
Ceratophyllum demersum
(
C. demersum) enables to remove elements from aquatic environments. Three treatments in four replications for purifying wastewater by
C. demersum were designed. The treatments included raw municipal wastewater (RMW) and treated municipal wastewater (TMW) and diluted compost latex (DCL). The experiment was performed at the open air of Khorasgan University area for 18 days without aeration. After this examination, the accumulation of Magnesium in
C. demersum indicated that the Magnesium in TMW, RMW and DCL were increased 96.29%, 100% and 73.52% respectively. These results demonstrate that in all of the treatments
C. demersum could absorb high Magnesium concentration from the aquatic environment. In addition, this investigation demonstrated that the amount of Calcium, Nitrogen, Phosphorous, Sodium and Potassium accumulated in
C. demersum absorbed efficiently from the aquatic environments respectively. Therefore, it was concluded that
C. demersum could be used to refine polluting metal from wastewater and could be the best biosorption method for protecting the water pollution in the environment.
