Nanomaterials, that is, materials on a nanometric scale, with dimensions less than 100 nm, using lignocellulosic waste (residual biomass) as raw material for synthesis, are a sustainable alternative, which contributes to the principles of green chemistry and the circular economy. The synthesis method used is based on a delignification process, promoted by pyrolysis, for this, a Nabertherm brand tubular muffle with a quartz tube was used. The process was carried out at temperatures of 500°C and 700°C for 1 or 2 hours in the presence of N2 flow, using a Proportional Integral Derivative (PID) controller, which generated Nano Activated Carbon (NCA), from cocoa shell.
Eutrophic systems resulting from poor management of domestic wastewater include negative consequences such
as human health, destruction of aquatic ecosystems and deterioration in water quality for human consumption. That is why we tested our NAC in liquid samples taken from Laguna de las Ilusiones, considered a Protected Natural Area of our State, to test the capacity of synthesized bioadsorbent nanomaterials contributing to efficient, modern, and low-cost technologies in the elimination of contaminants in real systems.
The adsorption experiments were carried out under conditions of 30 °C, reaching an efficient 70% removal. Furthermore, compared to materials treated with chemical agents, these reached 70% but with more severe conditions of 35°C. Therefore, the improvement in the economy of the process was achieved with the NAC synthesized by thermal treatment.
