Abstract

Surfactants pose a significant hazard to both ecosystems and human well-being. Given their ongoing and detrimental consequences, a growing number of researchers is concentrating on their eradication from aquatic habitats. Cellulosic nanofibrillar structures have garnered substantial attention recently as components in nanocomposites. This can be attributed to their wide availability, renewable and environmentally sustainable attributes, and exceptional mechanical properties. Due to the significant demand for natural fibres, unconventional bioresources, such as invading species that are destroying ecosystems and reducing biodiversity, must be found. Here in, we are reporting a sustainable approach for surfactant removal utilizing biodegradable natural fibres from Solanum viarum Dunal commonly known as Tropical Soda Apple (TSA) found abundantly in the Uttarakhand region. The fibrils are procured by employing a chemical retting process and are subsequently coated with a ZIF-8@ZIF-67 and chitosan to form a composite (ZCCF). The synthesized sample was analysed using X-ray Photoelectron Spectroscopy (XPS) to better comprehend its chemical structure and elemental makeup and Field Emission Scanning Electron Microscopy (FESEM) to understand the morphological changes in coated and non-coated fibres. Furthermore, this study proposes a sustainable approach for anionic surfactant Sodium Lauryl Sulphate (SLS) adsorption utilizing ZCCF. The composite demonstrated efficient adsorption of the SLS with a maximum adsorption capacity of 518.66 mg g−1 at pH 6.0.
