The significance of synthesized marine algae/ZnO nanoparticles for the degradation of sodium do-decyl sulphate: Response surface methodology

Abstract

Sodium dodecyl sulfate (SDS) is an organic compound used in many cleaning and hygiene products. This anionic surfactant called sodium dodecyl sulphate (SDS) is easily able to enter seawater through the discharge of home and commercial wastewater. The current study look into how marine algae nanoparticles breakdown SDS surfactant under diverse environmental conditions. Additionally, the various influences on the biodegradation process are researched and analysed using Response surface methodology. SEM analysis was used to determine the particle size. Synthesised ZnO-NP's crystalline structure is amply confirmed by XRD, and FTIR reveals the various functional groups that are present. The findings of this study demonstrated how the nanoparticle will affect several parameters including optimum time of 35 min, dosage of 0.35 g/lit, pH of 9, temperature of 313 K, and initial concentration of 100 ppm of SDS in aqueous solution. With the optimum conditions, we can successfully extract SDS from aqueous solution with a 93 % removal percentage.
