摘要: In this research, a novel adsorbent, tin sulfide nanoparticles coated on activated carbon [SnS-NP-C] was synthesized by simple, low cost and efficient procedure for the removal of methylene green from aqueous solutions. Subsequently, material characterization identification has been completed different techniques such as TEM, FT-IR, UV-Vis spectrometry analysis. batch experimental set-up, optimum conditions quantitative Methylene attained following searching effect variables adsorbent dosage (0.05-0.35 g), contact time (10-120 min), solution pH (6-10), initial concentration dye (10–60 mg/L) adsorption process investigated. Optimum values were set at 8.0, 0.25 g 50 min. Kinetic studies various show that maximum sequestered within 10 min sort time. The follows pseudo-second-order rate equation in addition to interparticle diffusion model (with more than 99%) all conditions. Equilibrium data fitted well with Langmuir amount while capacity 14.22 mg/g 0.2 [SnS-NP-C]. present is offers advantages shorter reaction time, simple workup, high percentage removal.
