Nanoporous carbon adsorbents derived from spent coffee grounds for CO2 capture

BACKGROUND Climate change has quickly emerged as a critical global challenge, with carbon dioxide (CO2) emissions considered the largest contributor to this climate crisis. These emissions are directly linked to shifts in weather patterns, an increase in extreme weather events, and the accelerated melting of polar ice caps. As climate impacts intensify,...

Nitrate removal from water by means of carbon adsorbents derived from spent coffee grounds

BACKGROUND High levels of nitrate ions in drinking water can pose health risks to humans and livestock. These nitrates can infiltrate drinking water by means of agricultural activities and wastewater. Fertilizers used in agriculture can be carried away by rainwater into nearby lakes and rivers. Wastewater from failed septic systems can also find its...
