Reusable SnSx filled PE+PET non-woven bag for effective degradation of cationic and anionic dyes

Abstract

This study explores the hydrothermal synthesis of Tin sulphide (SnS_x) nanoparticles at various pH levels and their application in the degradation of cationic and anionic dyes. The adjustment of pH during synthesis was found to significantly influence the crystal phase, size, and consequently, the optical and electronic properties of the nanoparticles. Characterization techniques such as Scanning Electron Microscopy (SEM) and X-ray Diffraction (XRD) revealed that the nanoparticles possess orthorhombic structures with average sizes ranging from 10 nm to 26 nm. These nanoparticles were employed to create filters that demonstrated exceptional reusability and stability over three cycles of degrading methyl blue (MB) and methyl red (MR) dyes. Notably, tin sulfide nanoparticles synthesised at low pH showed remarkable efficiency in degrading methyl red, indicating their potential for environmentally friendly water treatment applications.
