Studying the biochar modified by AgNO3 from coffee grounds to handle organic pollutants and microorganism in the seafood-processing wastewater

The aim of this study is to use four types of biochar modified AgNO3 from coffee grounds including CF5 (600°C/1.5h), CF6 (600°C/3h), CF7 (700°C/1.5h), and CF8 (700°C/3h) for the treatment of organic contaminants and microorganism in the seafood-processing wastewater. The results showed that the materials had the porous structure and the diameter of the pores corresponded to the crystal plane. The carbon content in the four samples reached over 90%.
