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 potentially responsible for cation sorption, and confirmed the toxic-metal bioaccumulation. The combine...
متن کاملDissolved organic matter release in a Posidonia oceanica meadow
We examined annual nutrient changes (nitrate, phosphate and ammonium) and the net dissolved organic carbon (DOC), nitrogen (DON) and phosphorus (DOP) release using in situ benthic incubations in a Posidonia oceanica meadow and in unvegetated sediments of Magalluf Bay (Mallorca Island, Spain) at monthly intervals. We also examined the role of the P. oceanica meadow in the C:N:P ratio transformat...
متن کاملUtilization of Modified Gloriosa superba Waste as an Adsorbent for the Removal of Reactive Dyes from Aqueous Solutions
Carbon prepared from Gloriosa superba pericarp was used to remove reactive orange 107 and reactive black 5 from aqueous solution by adsorption technique under varying conditions of agitation time, dye concentration, adsorbent dose and pH. Adsorption depended on solution pH, dye concentration, carbon concentration and contact time. Equilibrium was attained at 165 minutes and 105 minutes for reac...
متن کاملThe Perlite-calcium Alginate-activated Carbon Composite as an Efficient Adsorbent for the Removal of Dyes from Aqueous Solutions
To remove dyes from wastewater, the perlite-calcium alginate–activated carbon (PCA) composite was prepared by a simple method. This composite was characterized by FTIR, XRD, SEM, and BET techniques. A high capacity of PCA was observed for the adsorption of some dyes such as methylene blue (MB) and methyl orange (MO) from aqueous solutions (1111 and 909 mg g-1). The best results were achieved at...
