“…The use of chemical scale inhibitors is a common method to prevent scale formation, e.g. inorganic phosphates or green inhibitor (Boulahlib‐Bendaoud et al , 2012; Menzri et al , 2017). In the past few years, green inhibitors (Hasson et al , 2011; Chaussemier et al , 2015), have raised great interest because there are biodegradable, non‐toxic and do not affect environment (non‐bioaccumulation; Anastas and Warner, 1998).…”

In this study, the properties of quercetin (3,3′,4′,5,7-pentahydroxyflavone) solution towards CaCO 3 formation were evaluated by using chronoamperometry (CA) and impedance measurements. Quercetin a flavonoid present in plants as a secondary metabolite. Using CA, precipitation of CaCO 3 was totally inhibited by adding 2 mg/L of quercetin (T = 30°C). The same result was obtained by impedance measurements. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) were used to characterize the calcium carbonate scale without or with quercetin treatment. The predominant crystalline structure corresponds to a mixture of calcite and aragonite.
