Ultrasonic assisted synthesis of magnetic Ni-Ag bimetallic nanoparticles supported on reduced graphene oxide for sonochemical simultaneous removal of sunset yellow and tartrazine dyes by response surface optimization: Application of derivative spectrophotometry
Abstract
Simple and rapid simultaneous removal of sunset yellow and tartrazine from aqueous solution. A magnetic Ni-Ag NPs@ rGO hybrid adsorbent can be fast and efficiently separated. Utilizing the ultrasonic waves efficiently enhanced the removal of dyes from complex matrices. A first-order derivative spectrophotometry was applied for monitoring of dyes residuals. Application of RSM for modelling and optimization of variables affecting the removal process.
