We evaluated the potential use of agri-food waste for removal heavy metal ions from aqueous solutions and its application in different processes (e.g., water remediation, production biomass enriched nutritionally significant elements, etc.). Biomasses grape seed, pomace, loquat Calabrese broccoli stem, empty pods carob broad bean pods, unripe bitter orange peel, kumquat, pulp Canary Island banana were prepared. The percentages biosorption capacities compared with those refe-renced using...
A Schiff base-based fluorescent chemosensor has been studied for divalent copper detection. The formation of 2-hydroxybenzaldehyde benzoylhydrazone-Cu 2+ complex induced a fluorescence quenching this compound in medium water/ethanol (53% v/v) and 0.05 M phosphate buffer (pH 7.0). continuous variations mole-ratio plots absorbance suggested with 1:1 metal-ligand stoichiometry. conditional stability constant the was evaluated to be 6 × 10 −1 . modified Stern–Volmer relationship employed obtain...
The aim of this work was to compare the potential induction oxidative stress and antioxidant enzymatic response after a short-term waterborne exposure copper (Cu) arsenic (As) with that nanoparticles (NPs) these elements (Cu-NPs As-NPs) in fish larvae species Dicentrarchus labrax. Larvae were grouped several tanks exposed different concentrations contaminants (0 10 mg/L) for 24 or 96 h under laboratory conditions. Copper analysed larval tissues using ICP-MS. A set biomarkers, including...
A new biosorbent obtained from Calabrese broccoli stalks has been prepared, characterised and used as an effective, low-cost ecofriendly biomass to remove Pb(II) aqueous solutions, without any complicated pretreatment. Structural morphological characterisation were performed by TGA/DGT, FTIR SEM/EDX; the main components are hemicellulose, starches, pectin, cellulose, lignin phytochemicals, with important electron donor elements (such S glucosinolates of broccoli) involved in sorption. The...
Environmental context Metal contamination of seawater can present severe environmental problems owing to the high toxicity metals and their persistence in environment. This study explores possibility analysing lead media using two recently developed electrochemical methods. The methods are shown be very useful tools monitor behaviour fate other seawater. Abstract speciation PbII synthetic real is studied by absence gradients Nernstian equilibrium stripping (AGNES) chronopotentiometry at...
