Abstract
A melamine-formaldehyde derived porous carbon adsorbent may be prepared from melamine-formaldehyde derived porous carbon disposable products. The melamine-formaldehyde derived porous carbon effectively removes organic pollutants from aqueous media. Parameters of contact time, solution pH, initial adsorbate concentration and desorption rate affect efficacy. Adsorption capacities of exemplary melamine-formaldehyde derived porous carbon for MG and MB dyes at 298 K were up to 25 mg/g and 35 mg/g, respectively.
