This review responds to the ongoing needs of wastewater engineers tasked with treating aqueous solutions containing chelated complexes of metal ions, of which nickel citrate in electrodeless plating and copper–EDTA in electronic chip board manufacturing are two key examples. Because of the presence of these sequestering agents, metallic ions cannot be readily precipitated by alkalinity, making a compelling case for the discovery of alternative methods of treatment. This review is a critical appraisal of the varying degrees of success in separation process strategies deployed for the recovery of metallic ions under such challenging chemical conditions. Guidance is provided on making progress toward satisfactory industrial solutions to surmount these difficulties. © 2014 American Institute of Chemical Engineers Environ Prog, 34: 761–783, 2015

“…The constant n presents the intensity of concentration influence on adsorption, and K F is regarded as the adsorption when C e is unit concentration. Freunlich equation is characterized by a distinct theoretical foundation that adsorption action is multimolecular layer and adsorption will increases at all hours, which prevents saturation adsorption quantity from acquiring [35,36]. The relation coefficient R 2 fitted with Freunlich equation is 0.929, which is not satisfactory.…”

A microsphere biosorbent with uniform size (CV = 1.52%), controllable morphology and component, and high mechanical strength was synthesized from chitosan by microfluidic technology combining with chemical crosslinking and solvent extraction. This chitosan microsphere (CS-MS) was prepared with a two-step solidification process, which was acquired by drying for the enhancement of mechanical property in final. The adsorption behavior of CS-MS towards copper (II) and main influencing factors on adsorption performance were investigated by batch experiments. Kinetic data highlighted dominant chemical bonding along with electrons transferring in adsorption process. Isothermal analysis indicated that adsorption capacity was relevant to the number of active site. All these explorations provided a new direction for preparing highly comprehensive performance sorbent used in heavy metal treatment via microfluidic technology.

. Kinetic adsorption data were analyzed using the pseudo-fi rst-order kinetic model, the pseudo-second-order model and the intraparticle diffusion model. The adsorption kinetics well fi tted using a pseudosecond-order kinetic model. The experimental isotherm data were analyzed using two isotherm models, namely, Langmuir and Freundlich. The results revealed that the adsorption behavior of the RB onto ZnFe-NC fi tted well with the Langmuir isotherm model. In addition, various thermodynamic parameters, such as standard Gibbs free energy (ΔG
