Adsorption of Cu (II) and Cd (II) from Wastewater by Sodium Alginate Modified Materials
Figure 10
The removal efficiency of SACL for wastewater Cu (II) and Cd (II) after four adsorption-desorption cycles (experimental condition: Cu (II) concentration = 200 mg·L−1; Cd (II) concentration = 200 mg·L−1; contact time = 180 min; amount of adsorbent = 4 g; pH = 4; and agitation speed = 150 rpm) (error bars represent the standard deviation of three replicates).
