Heavy Metal Biosorption Characteristics of the Submerged Aquatic Plant (Nasturtium officinale)
Asian Journal of Chemistry,
Vol. 22 No. 1 (2010): Vol 22 Issue 1, 2010
Abstract
In the present investigation an aquatic plant, Nasturtium officinale
was examined for its biosorption ability of heavy metal ions. The results
obtained from biosorption experiments were used to understand the
driving forces that govern the interaction between metal ions and
biosorbent. The experimental biosorption data were fitted to the
Scatchard plot, Langmiur and Freundlich isotherms. According to the
parameters of the Langmiur isotherm, the maximum biosorption capacities
of Cd2+ and Co2+ were 0.56 and 0.49 mg/g, respectively. In view
of Freundlich isotherms, the maximum biosorption capacities of Cd2+
and Co2+ were 2.23 mg/g for both of metal ions.
