Abstract
Arsenic in water and wastewater is considered to be a critical contaminant as it poses harmful health risks.In this regard, to meet the stringent regulation of arsenic in aqueous solutions, nitrogen doped carbon-based materials (CN) were prepared as adsorbents and tested for the removal of arsenic ion from aqueoussolutions. Nitrogen-doped carbon (CNs) synthesized by chlorination exhibited well-developed micro-and small meso-pores with uniform pore structures. The structure and characteristics of the adsorbentsthus developed were confirmed by field-emission scanning electron microscopy, transmission electronmicroscopy, Brunauer–Emmett–Teller analysis, X-ray diffraction, X-ray photoelectron spectroscopy, andFourier transform infrared spectroscopy. Among the CNs developed, CN700 exhibited high adsorption
