INHIBITION STUDIES FOR THE METALLIC CORROSION OF TIN (SN) IN ACID (HCL) MEDIUM USING UMBRELLA LEAF (SCHEFFLERA ACTINOPHYLLA) AS INHIBITOR
Abstract
ABSTRACT
This study investigates the inhibition effect of umbrella leaf extract on the corrosion of tin in hydrochloric acid (HCl) medium. The corrosion behavior was evaluated using weight loss measurements. Various concentrations of the leaf extract were tested, revealing that the extract significantly reduced the corrosion rate of tin in the acidic medium. The inhibition efficiency increased (with Highest Value as 83o/o) with the concentration of the extract. (as 0.9 concentration). The presence of functional groups in the extract, such as tannins, saponins, and flavonoids, was confirmed by Fourier transform infrared spectroscopy (FTIR), contributing to the formation of a protective layer. The study concludes that Schefflera Actinophylla is an environmentally friendly and effective corrosion inhibitor for tin in HCl solution.
