Biosorption of Cr(III) and Pb(II) by Schoenoplectus californicus and Insights into the Binding Mechanism
Figure 4
Sorption of Cr(III) and Pb(II) by the biomass of S. californicus as a function of the biosorbent dose at pH 5 ± 0.1 (a) and 7 ± 0.1 (b) (initial metal concentration: 1.5 mM; temperature: 25°C). Vertical bars indicate the standard deviation of three replicates, and the letters indicate the groups that correspond to the significant () differences.
