Considering the growing environmental concerns about the discharge of saline water coming from desalination systems, the present work is of significant interest. The effect of LEO ( Lycium Essential Oils) as green inhibitors of calcium carbonate scale has been investigated in this study. We used conductivity measurements, nanoparticles-doped membranes technologies, electrochemical impedance spectroscopy (EIS), and chronoamperometry techniques. The calcium carbonate scale was deposited from the brine solution by cathodic polarization of the steel surface. The observed anti-scaling property can be partly explained by the presence of plant antioxidants. Antioxidants retarded calcium carbonate precipitation via the formation of a complex with the calcium cations. Without LEO, adherent film formed over the steel surface, under cathodic polarization, by the deposition of the calcium complex.
