Selective recovery of trace Ga(III) using a regenerable gallic-acid–grafted bio-graphene

Key Points

• The selective recovery of gallium from solutions highlights significant advancements in metal recycling.
• Metric analysis indicates high recovery rates, achieving up to 90% gallium recovery with bio-graphene.
• Assessment using adsorptive properties shows enhanced performance due to gallium grafting methods.
• This method may enable improved recycling practices but needs further studies on industrial applications.
