Tin sulfide NANOPARTICLE LOADED ONACTIVATED CARBON AS AN ADSORBENT FOR THE REMOVAL OF Methylen green FROM AQUEOUS SOLUTION

In this research adsorption and removal of Methylen green from aqueous solution using Tin sulfide nanoparticleloaded on activated carbon (SnS-NP-AC) has been investigated. Equilibrium data are mathematically modeled using the Freundlich Langmuir, Tempkin and DubininRadushkevich (D–R) adsorption models. The Methylen green adsorption kinetics on to SnS-NP-AC was studied in terms of pseudo-first-order, pseudo-second-order, Intra particle diffusion and Elovich models. A maximum adsorption capacity of 99.909 mg.g-1 based on Langmuir as most applicable model at equilibrium is achieved. The high capacity and low removal time show the suitability and usefulness of SnS-NP-AC alternative adsorbent for the removal of Methylen green in wastewater treatment.
