Open AccessHeteroatom-enriched and renewable banana-stem-derived porous carbon for the electrochemical determination of nitrite in various water samples
For the first time, high-surface-area (approximately 1465 m2 g−1), highly porous and heteroatom-enriched activated carbon (HAC) was prepared from banana stems (Musa paradisiaca, Family: Musaceae) at different car...
