Green synthesis of gum Arabic-activated magnetite–nickel nanoparticles for selective removal of Cd( ii ) and Cu( ii ) from complex aqueous systems

Type: article

Abstract: , respectively, were obtained with optimal performance at pH 6.0, 4.0 g per L dosage, and 240 min contact time. Kinetics follow a pseudo-second-order model, while isotherms fit Langmuir and Sips models, indicating monolayer chemisorption as described by the Langmuir model, alongside surface heterogeneity captured by the Sips model. The material showed higher affinity for Cd(ii), achieving 64% selectivity in binary and 58% in multicomponent systems. These results underscore GA-NiMMPs as a promising bio-derived adsorbent for sustainable Cd(ii) and Cu(ii) remediation in complex waters.
