Optimization of Kaolin adsorbent to reduction iron metal ion using ultrasonic technology

Abstract

This study was to adsorb of metal ion in water solution by modifying kaolin with anionic surfactant and ultrasonic irradiated. The purpose of this study was to optimize the absorption of metals more specific in absorbing Fe metals in water using modified kaolin with anionic surfactants and ultrasonic irradiated. The adsorption process was carried out using a surfactant modified kaolin modification and without surfactant modification with irradiation time variations of 5, 10, 15, 30, 50 and 80 min at 55 - C. Samples were analysed using Atomic Absorption Spectrophotometers (AAS), while their characteristics used Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscope (SEM). The results showed that the maximum removal efficiency of kaolin modification occurs faster than that of kaolin without modification. The maximum allowance for kaolin modified removal efficiency reached 72.81% at 30 minutes irradiation time, while for kaolin without modification the removal efficiency was 65.1% at 30 minutes irradiation time.
