A novel acidic ball milling method was designed to fabricate porous biochar directly from hickory wood, which showed higher adsorption capacity for organic dyes. This method has the potential to be a convenient and efficient approach for environmental remediation and water treatment applications.
Biochar has attracted considerable attentions for its potential in many environmental and industrial applications. Here, a novel facile and efficient one-step acidic ball milling approach was designed to fabricate a porous biochar directly from hickory wood without any external heat treatment. After characterization, the biochar was tested for its ability to remove Titan Yellow (TY) organic dye from aqueous solution. Compared to the pristine ball milled biomass (BMB), the acidic ball milled biochar (ABMB) had a greater degree of carbonization and a larger diversity of oxygen-containing functional groups. As a result, the ABMB sorbed 23 times more TY dye than BMB (maximum sorption capacities of 182.3 and 8.1 mg g(-1), respectively). Freundlich isotherm and intraparticle diffusion kinetic models best described the TY adsorption by ABMB and BMB. The results suggest that the onestep acidic ball milling method has great potential as a convenient and efficient approach to convert biomass to biochar with excellent characteristics for environmental remediation and perhaps water treatment applications.
