Title : Green synthesis and characterization of ZnO/NiO nanohybrid for mitigation of basic brilliant flavine Y-40 dye: An environmental clean strategy


The removal of synthetic dyes has become a serious concern due to their lethal environmental effects. Nickel oxide and zinc oxide nanoparticles (NPs) were synthesized using extract of Prunus armeniaca leaves. The synthesized NPs were characterized by FTIR, SEM, Zeta, and XRD analyses and were applied for the remediation of Basic Brilliant Flavine Y-40 dye folloowinf thye optimization of various experimental factors like dye concentration, nanoparticle concentration, pH, H2O2 concentration, and temperature. The highest dye decolorization was observed at dye concentration of 0.001% in combination with hybrid nanoparticle ratios of 1:2 (ZnO:NiO) at 40 oC, pH 6, and  level of H2O2 0.004%. The dye samples were assessed via water quality parameters. The reduction in COD and TOC levels were found to be 87.6% and 85.3%, respectively, compared to the untreated samples and the toxicity assessment demonstrated the biocompatibility of the NPs. Kinetic studies and catalyst reusability studies were also carried out.

Audience Take Away

  • Use of nanotechnology in the green synthesis of metal or metal oxide nanoparticles
  • The approach of green synthesis of metal oxide nanoparticles is a cost-efficient, eco-friendly, and easy alternative approach
  • Nanoparticles are helpful in the removal of synthetic dyes, hence controlling water pollution


Dr. Shumaila Kiran studied Chemistry at the University of Agriculture, Faisalabad, Pakistan, graduated as MS in 2006. I received her PhD degree in 2012 at the same institution. I obtained the position of an Assistant Professor at the Government College University, Faisalabad, Pakistan in 2012 and currently working as an Associate Professor in the same institution since 2019. I have published more than 65 research articles in well reputed ISI listed international well-reputed journals.
