Figure 1

The mass of MC-LR adsorbed by binding gel in 20 mL solutions containing 200 μg L−1 MC-LR and 0.01 M NaCl. The Y axis refers to the ratio of mass of MC-LR adsorbed by the HLB gel divided by the mass contained in the initial solutions. Error bars are calculated from the standard deviation of the replicates (n = 3).
