Fluorescent Sensing of Fe in Acidic Environment by Carbon Dots Derived From Empty Fruit Bunch Biochar: Central Composite Design Optimization.

A rapid, eco-friendly, and selective monitoring of Fe(III) in real media utilizing carbon dots (CDs) as a luminescence detector has been reported. CDs were fabricated by a hydrothermal route from empty fruit bunch biochar. The as-synthesized CDs were analyzed using various analytical tools.
