The process of synthesizing biochar from agricultural by-products for the treatment of dyes and antibiotics in water environments.

Abstract

The invention proposes a process for synthesizing biochar from agricultural by-products, preferably avocado peel, by alkaline activation with KOH and aerobic pyrolysis; The process includes the following steps: material preparation; preliminary activation with KOH solution; pyrolysis under aerobic conditions; washing and drying of biochar; evaluation of product characteristics; The obtained biochar has a large surface area (800-900 m2 / g), contains active functional groups (-OH, -COOH, C=O), and exhibits high adsorption efficiency for Methylene Blue (>95%) and Ciprofloxacin (>90%); The product is reusable after multiple cycles, suitable for applications in treating colored and antibiotic-contaminated water at both household and industrial scales.
