In the International Journal of Electrochemical Science, Hongzheng Yang et al. explore the dual functionality of nano-biochar derived from bamboo biomassBiomass is a complex biological organic or non-organic solid product derived from living or recently living organism and available naturally. Various types of wastes such as animal manure, waste paper, sludge and many industrial wastes are also treated as biomass because like natural biomass these More for electrochemical sensing of ferulic acid and adsorptive removal of surfactants in cosmetic wastewater. This research highlights nano-biochar’s potential in both analytical and environmental applications within the cosmetic industry. Nano-biochar, a nanostructured carbon material, is derived from biomass and possesses unique properties that make it suitable for electrochemical sensing and adsorption.  

The study demonstrates that nano-biochar can be used for electrochemical sensing of ferulic acid, a compound widely used in cosmetics due to its antioxidant, anti-inflammatory, and anti-aging properties. The nano-biochar modified glassy carbon electrode exhibited excellent electrocatalytic activity towards ferulic acid oxidation. In addition to sensing, the nano-biochar also demonstrated high adsorption capacities for the removal of surfactants from simulated cosmetic wastewater. Specifically, it showed high adsorption capacities for sodium dodecyl sulfate (SDS) and cetrimonium bromide (CTAB). The synthesis of nano-biochar involves using bamboo biomass, a widely available resource. The bamboo is washed, dried, and then processed to create nano-biochar. The resulting nano-biochar has a high surface area, excellent electrical conductivity, and rich surface functional groups, making it ideal for various applications.  

This research showcases the potential of nano-biochar as a dual-functional material that can address both analytical and environmental challenges in the cosmetic industry. Its application in electrochemical sensing allows for rapid, on-site analysis of ferulic acid in cosmetic products and wastewater. Additionally, its adsorptive properties enable the effective removal of surfactants from cosmetic wastewater, offering a sustainable and eco-friendly solution for wastewater treatment. The use of nano-biochar aligns with the growing demand for green analytical methods and sustainable wastewater treatment solutions.
