Nickel Removal by the Aquatic Plant (Ceratophyllum Demersum L.)

M. Chorom, A. Parnian, and N. Jaafarzadeh

Abstract—Phytoremediation with aquatic plants is a new, effective and inexpensive method for improving water quality and wastewater. In this study, Nickel removal by the aquatic plant, coontail (Ceratophyllum demersum L.), native hydrophyte of most of Iran’s rivers, was reviewed after optimum growing pH nomination, within 14 days cultivation in contaminated Hoagland nutrient solution, at the four different concentration of nickel (0, 1, 2, 4, and 6 mg L-1). With daily analysis of nickel concentration in cultivation solution and also initial and final concentration of this element in plant, nickel phytoextraction potential evaluated, and nickel biological effects on coontail grows with biomass production was studied. Maximum removal efficiency was 50% calculated from 6 mg L-1metal concentration. Maximum bioconcentration factor and maximum uptake index calculated from 6 mg L-1 metal concentration were 338.65 and 5.05 mg, respectively. Maximum(3.6 g/day) and minimum (1.27 g/day) biomass production index caused from 0 mg L-1 and 6 mg L-1 of pollutant concentrations. Based on the results, nickel phytoremediation of industrial wastewater by coontail is applicable.

Index Terms—Nickel, wastewater, phytoremediation, aquatic plant.
