The antiscale properties of the aqueous extract of olive (Olea europaea L.) leaves as a natural scale inhibitor for stainless steel surface in Hammam raw water were investigated using chronoamperometry (CA) and electrochemical impedance spectroscopy techniques in conjunction with a microscopic examination. The X-ray diffraction analysis reveals that the scale deposited over the pipe walls consists of pure CaCO calcite. The CA, in accordance with electrochemical impedance spectra and scanning electron microscopy, shows that the inhibition efficiency increases with increasing extract concentration. This efficiency is considerably reduced as the temperature is increased.
采用计时电流法（CA）和电化学阻抗谱技术，并结合微观检查，研究了橄榄（油橄榄）叶水提取物作为哈马姆原水中不锈钢表面天然阻垢剂的阻垢性能。X射线衍射分析表明，沉积在管壁上的水垢由纯碳酸钙方解石组成。计时电流法与电化学阻抗谱和扫描电子显微镜的结果一致，表明随着提取物浓度的增加，缓蚀效率提高。随着温度升高，这种效率会大幅降低。
