“…The final pH of 1:3 Cd:citrate medium was higher than that of 1:2 Cd:citrate medium, therefore, the residual citrate concentration in the 1:3 Cd:citrate medium was lower than that in 1:2 Cd:citrate medium. This result was in agreement with the degradation of Ni-citrate complex [10]. Whereas, due to the limitation of pH increase in the 1:2 and 1:3 Cd:citrate media, citrate complexed with Cd could not be completely dissociated for metabolism.…”

“…Our previous research showed that addition of Fe 3+ resulted in the complete transformation of Ni-citrate complexes, and we speculated that displacement-degradation mechanism was responsible for this phenomenon [10]. The displacement-degradation mechanism might also be responsible for the complete biotransformation of Cd-citrate complex in the 1:1:2 Fe:Cd:citrate and Zn:Cd:citrate media.…”

“…Huang et al investigated the biotransformation of non-biodegradable U-citrate complex at alkaline pH, they found that over 99% of the citrate was metabolized by bacteria, and speculated that dissociation of citrate from U-citrate complex at alkaline pH raised the bioavailability of citrate [9]. Whereas, for Ni-citrate complex, limited biodegradation of citrate was observed due to the formation of tridentate Ni-citrate complex at alkaline pH [10].

“…Games and Staubach [38] attempted to compare the rates of ozonation of unbound and chelated nitroloacetic acid (NTA, of Mg, Cu, and Zn); however, the results were inconclusive.

Gilbert and Hoffmann-Glewe [40] also compared the rates of ozonolysis of 1:1 EDTA chelates, studying the rate of degradation of EDTA (10 23 mol dm 23 ) by ozone in the presence of metallic ions.…”

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 feasibility of biometallurgical processing for recovering heavy metals, precious metals, and rare earth elements from waste electrical and electronic equipment (WEEE) is critically reviewed. An overview of past achievements, present scenarios, and future prospects of these techniques is given. The potential of various lithotrophic and organotrophic microorganisms is particularly highlighted for extracting metals by producing inorganic and organic acids in the process. The metal‐binding ability of various biomaterials including algae, fungi, bacteria, and yeast as well as certain biopolymers and biowaste materials, is reviewed in view of recovering metals from WEEE. Due to the increasing importance of heavy and precious metals and rare earths elements in the transition to a green energy economy based on high‐tech applications, coupled with the shortage of economical and/or operational primary deposits, a substantial improvement in the recycling of WEEE for recovery of metals is therefore an absolute necessity. This can only be realized by developing efficient and fully integrated recycling routes. Current work also focused on most probable recycling routes, with an emphasis on the state of the art in bioprocessing of WEEE.
