Efficient Adsorptive Removal of Methyl Violet Dye from Wastewater Using Functionalized Groundnut Shell Biochar: Application, Mechanism, Modeling, and Optimization Study

Global Challenges, Volume 10, Issue 9, September 2026.
This study focused on the production and application of secondary waste, namely ground nutshell residual mass (after MeOH extraction)‐derived FGNB‐based multifunctional nanoadsorbents in industrial wastewater treatment technology. The FGNB nanosorbent would be a sustainable alternative to fossil‐based, hazardous ones for environmental protection and ...
