Inhibitory effect of glutamic acid on the scale formation of drinking water

Abstract

The formation of calcium carbonate in water has some important implications in geoscience researches, ocean chemistry studies, CO2 emission issues and biology. In industry, the scaling phenomenon may cause technical problems such as reduction of heat transfer efficiency in cooling systems and obstruction of pipes. This paper focuses on the study of the glutamic acide (GA) for reducing calcium carbonate scale formation on metallic surfaces using the water of region of Ouargla, chemical and electrochemical study of this water shows a high calcium concentration and characterization of formed deposit reveals the formation of calcite. Their antiscaling properties have been evaluated by the chronoamperometry method and electrochemical impedance spectroscopy (EIS) in conjunction with a microscopic examination..
