- •
Macroalgae as natural cation exchangers for the treatment of galvanic wastewater.
- •
Raw Laminaria hyperborea showed a higher affinity for zinc from the galvanic effluent.
- •
The zinc ions were easily displaced from the exhausted biomass using acid eluents.
- •
The regenerated Ca-loaded alga showed similar performance to raw Ca-alga.
- •
Na-loaded alga showed severe physical deterioration due to alginate solubilization.
