Phytoremediation Study of Water Hyacinth (Eichhornia Crassipes) on Zinc Metal Ion (Zn2+)

The high level of community activity around the river has resulted in levels heavy metals contained water. Commonly found such as zinc (Zn), mercury (Hg), and copper (Cu). To reduce or remove waters, phytoremediation techniques are used. purpose this study was to determine ability water hyacinth plants (E. crassipes) remediating Zn2+ metal contaminated Lake Tempe research method used includes sampling process, acclimatization, physicochemical analysis, Zn Bio-Concentration Factor (BCF), infrared (IR) analysis. concentration decreased after 30 days process. And highest adsorbed (II) ions on 77,257 ppm 30th day. It that there is a relationship between BCF value time, higher obtained. IR data show presence bonds involving functional groups C=S, C=N, OH. This indicates potential be agent adsorbing waters.
