Improving Spent Coffee Biochar for Effective Organic Contaminant Removal from Aqueous Media.

ABSTRACT: The contamination of (waste)water with organic pollutants, such as pharmaceuticals and dyes, is drastically increasing. Their removal process presents several difficulties, and often activated carbon (AC) is used in a filtration step. While commercial AC is often based on fossil resources, in this study, we present a new approach toward biochar from spent coffee (SC). This new AC has considerably enhanced surface areas and porosities, making it suitable for wastewater treatment. Using MgCO₃ as an activating agent, a biochar with a significantly enhanced surface area of ∼600 m²/g is produced in a simple but efficient manner. The resulting biochar is effective for the removal of a whole spectrum of organic pollutants in aqueous systems. The dyes methylene blue (MB) and
