Inhibition Study of Piper betle Leaf Extracts to Calcium Carbonate (CaCO_3) Scale Formation

摘要

Inhibition study of Piper betle leaf extracts to calcium carbonate (CaCO_3) scale formation has been carried out using seeded experiment method. This study was conducted at concentration of CaCO_3 growth solution of 0.075 M and at the temperature of 90 °C. The concentration of the Piper betle leaf extracts added in the growth solution of CaCO_3 were 250-450 ppm. It was observed that the typical conditions were found to be efficiently inhibit the scale formation process by performing Scanning Electron Microscopy (SEM) to evaluate the morphology changes of CaCO_3 crystals. The data obtained from the investigation reveals that the ability of Piper betle leaf extracts as a green inhibitor of the CaCO3 scale formation is around 30.16-46.65%. This finding support the Piper betle leaf potential as a scale inhibitor.
