Removal of vanadium(III) and molybdenum(V) from wastewater using Posidonia oceanica (Tracheophyta) biomass.

The use of dried and re-hydrated biomass of the seagrass Posidonia oceanica was investigated as an alternative and -low-cost biomaterial for removal of vanadium(III) and molybdenum(V) from wastewaters. Initial characterisation of this biomaterial identified carboxylic groups on the cuticle as potent...
