Abstract
Ultrasound (US) application and sonochemical reactions in various environmental processes are gaining importance. In this regard, liberation of iodine obtained through oxidation of potassium iodide (KI) using US has been studied in the present work. This method finds wide application of oxidation process in various applications such as unit process reactions, synthetic chemistry as well as waste remediation. Process parameters such as time and ultrasound power have been investigated. Liberation of iodine from the reaction system has been analyzed using UV-Visible spectrophotometric method through iodometry. Maximum liberation of iodine was obtained using ultrasound (25 W, 20 kHz) for 30 minutes treatment with 10 ml of 16.6% KI solution. The study finds potential use in sonochemical based oxidation reactions and environmental processes.
