چکیده مقاله:

Organic dyestuffs and dye-manufacturing wastewater are currently a major problem for environmental managers.1 Various treatment processes such as adsorption, coagulation, flocculation, reverse osmosis, photo-degradation process and ion-exchange have been used to remove dyes from wastewater.2 Because of its low cost and ease of operation, adsorption method has attracted many attentions to remove dyes.3 The literature review shows that the application of magnetic adsorbents for removal of waste waters pollutants has been frequently documented. The magnetic adsorbents are easily separated from the solutions using an external magnetic field and therefore have the possibility of reusing for further examinations.4 In this work, we report a facile approach to prepare the magnetic cobalt nanoparticles supported on cellulose (Co NPs/Cellulose). The prepared nanocomposite exhibited a perfect affinity towards removal of congo red (CR) from aqueous solutions and due to the magnetism of Co NPs is very easy to separate from treated solution.
