Dual Functional Neodymium-Yttrium Binary Oxide for Nanomaterials and Environmental Remediation

Strategic Insights

— 1 min read

Recent research from the Dr. B.R. Ambedkar National Institute of Technology has yielded promising results for using neodymium-yttrium oxides (NYO) in nanomaterials. NYO has been found to be an effective adsorbent for removing harmful substances from textile wastewater, specifically Congo red (CR) dye. In addition to adsorption applications, NYO has also demonstrated its potential as a sensitive sensor for detecting cyanocobalamin, a B12 vitamin. The sensor developed for cyanocobalamin detection showed excellent performance, with a wide linear range of 5-95 nM and a detection limit of 5.12 nM. These findings highlight the potential of NYO nanomaterials for both environmental remediation and biotechnological applications.

Key Takeaways:

  • NYO nanomaterials have been found to be highly effective adsorbents for removing Congo red dye from textile wastewater, with a removal efficiency of 90.9% at an optimal dose of 10 mg/30 mL.
  • The adsorption behavior of NYO has been well-described by the Langmuir isotherm model and pseudo-second-order kinetics model.
  • Reusability tests demonstrated that the nanomaterials could be reused for six cycles, maintaining an adsorption efficiency of 68.5%.
  • NYO nanomaterials exhibited stable and reproducible fluorescence responses, with selective recognition of cyanocobalamin.
  • The sensor developed for cyanocobalamin detection demonstrated excellent performance, with a wide linear range of 5-95 nM and a detection limit of 5.12 nM.
  • The research highlights the potential of NYO nanomaterials for both environmental remediation and biotechnological applications.
  • Dr. Jyoti Duhan, Dr. Bindu Dhuva, and Dr. Sangeeta Obrai were the authors of this research study.

Statistics:

  • 90.9% removal efficiency of Congo red dye using NYO nanomaterials at an optimal dose of 10 mg/30 mL.
  • 10 mg/30 mL optimal dose of NYO nanomaterials for maximum adsorption of Congo red dye.
  • 68.5% adsorption efficiency maintained by NYO nanomaterials after six reusability cycles.
  • Detection limit of 5.12 nM for cyanocobalamin detection using the NYO-based sensor.
  • Linear range of 5-95 nM for cyanocobalamin detection using the NYO-based sensor.
