Title : Mitigation of direct orange 26 dye using copper nano particles synthesized from tilapia fish scales: An environmental remedial approach
Abstract:
The performed work reports the manipulation of a collective local surplus solid (fish scales of tilapia) for the synthesis of copper nanoparticles. Copper nanoparticles were synthesized using tilapia fish scales and were characterized using SEM and XRD. The synthesized copper nanoparticles were used for the remediation of direct orange 26 dye. The maximum remediation (90.2%) was noted at 0.01 g/L concentration of dye, 0.001 g/L of Cu-NPs, pH 8, at 40 ºC. The value of TSS for untreated and treated solutions was found to be 0.447 mg/L and 0.40 mg/L, respectively. Similarly, the value of TDS for the untreated solution was found to be 22.35 mg/L while for the treated solution it was 20 mg/L. The percent reduction in COD and TOC were 84.54% and 86.76%, respectively. All data was analyzed statistically. The current study inferred that copper nanoparticles using a tilapia fish scale which is a bio-waste material could be successively used for the detoxification of other toxic dyes as well.
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
