Abstract

Abstract. The application of natural green inhibitors to inhibit scale formation of inorganic materials have become a necessity these days considering the many inhibitors are used in the industry are not environmentally friendly and expensive. In this research, it has been investigated the green inhibitors from natural products called LS Inhibitor. Analysis with the GC-MS (gas chromatography–mass spectrometry) shows that the main chemical compositions of LS inhibitor consisted of acetic acid (more than 50 %) and phenol (more than 15 %). Testing of LS inhibitor was performed by seeded experiment method at temperature of 90 °C and concentration of calcium carbonate (CaCO3) growth solution of 0.050 M. The results showed that the higher the inhibitor concentration added the greater the effectiveness of the inhibitor in inhibiting the formation of CaCO3 crystals accompanied by the decrease in pH of the solution. It is concluded that the addition of LS inhibitor in the concentration range of 50-350 ppm in CaCO3 crystal growth solution at the concentration of 0.050 M is able to inhibit the scale formation of CaCO3 around 27-278 %.
