Abstract

Remediation of industrial water pollution is a trending subject to date for the researchers around the globe, due to its detrimental effects on human life as well as aquatic life. Azo dyes are the largest industrial water polluters in respect of volume while anthraquinone the second largest. Therefore, humongous considerations are being enumerated for the removal and decolorization of azo (AZ) dyestuff; however, for anthraquinone (AQ) dyes, these efforts are considerably minimal; although the later one poses a greater threat to environmental contamination, because of their reinforced structure. The current study is an effort toward this foremost issue. Chemical reduction synthesis of silver-copper (Ag-Cu) bimetallic nanoparticles (BNPs) was achieved using NaBH4 as a reducing agent and sodium dodecyl sulfate (SDS) as a stabilizer. Characterization and morphological evaluation indicates two distinctive UV/vis absorption peaks for Ag and Cu. XRD studies for nanocomposite showed crystallite size of 8.96014 nm having an FCC structure. SEM with EDX confirmed the particle sizes of BNPs and SDS to be 17.14 and 114.56 nm, respectively. Potential catalytic activity and kinetic parameters of Ag-Cu BNPs@SDS were monitored against Methylene Blue (MB), Methyl Orange (MO), and eosin-y (EY). The percentage degradation recorded for the nanocatalyst against MO, MB, and EY was 95.21%, 98.57%, and 96.65%, respectively. This method can be adopted for the removal of multiple dyes from industrial effluent on a larger scale.
