APPLICATION OF BIO-ADSORBENT DERIVED FROM ANNONA GLABRA SEEDS IN THE REMOVAL OF METHYLENE BLUE

Abstract

Currently, waste products from biological materials are widely used for water treatment in Vietnam and other nations across the world. Due to the rapid industrialization and modernization, the use of water treatment materials derived from waste products in the process of industrial production is raising great concern and attention. Binh bat seeds were processed into methylene blue treatment materials in water for this study. In the pH range of 2 to 10, the color adsorption capacity of the material gradually increased from 13.4% to 86.9%, while the similar tendency was observed as the adsorbent’s dosage rose from 10mg to 35mg, making the color absorption capacity increased from 75.2% to 87.9%. The results suggested that biological materials for water treatment could be an appropriate alternative for other conventional materials, with the advantage of low costs boosting the economic benefit of those materials in water/wastewater treatment technology.
