Removal of methylene blue by perilite clay-MnO2 nanocomposite

Abstract

In this study an attempt has been made to study the feasibility of removal of methylene blue using perilite-MnO2 nanocomposite as an adsorbent. The commercially available Perilite and MnO2 are stirred with alcohol, dried and used. Batch adsorption experiments have been conducted under various operating parameters like initial dye concentration, contact time, adsorbent dose and pH. The equilibrium data fitted well with the Langmuir and Freundlich isotherms.
