Improving the Method for Producing Adsorbents from Agro-Industrial Wastes
A multi-stage method for producing an absorbent with increased absorption capacity based on agro-industrial wastes has been proposed. The method includes treatment of raw materials with sulfuric acid, mechanochemical modification, electrostatic separation, and cavitation stage. The expediency of the proposed adsorbent usage in the process of purification of contaminated water from fats, phenols, petroleum products, and heavy metal ions has been proved. The complex application of adsorbents (absorption of gaseous pollutants and wastewater purification) has been tested.
