“…In suspension polymerization, monomers are dispersed into monomer droplets in the dispersed phase containing water, monomer, initiator and porogen, and suspended in water under the action of agitation and dispersant [ 19 ]. The monomer droplet is equivalent to a small reactor for bulk polymerization, and its polymerization mechanism is the same as that of bulk polymerization [ 42 ].…”

“…The direct method refers to that of forming IIPs directly on the electrode surface, which can be divided into in situ polymerization and electropolymerization [ 19 , 58 ]. In situ polymerization is a method of mixing functional monomers, template ions and initiators under certain conditions such as light or heat, and then applying them to the electrode surface for polymerization to form ion-imprinted membranes (IIMs).…”

“…MIECSs have attracted extensive attention owing to their specific recognition, rapidity, simplicity, and low cost, and have been successfully used to detect various molecules ranging from dangerous small molecules to biological macromolecules [ 17 , 18 ]. Ion imprinting technique (IIT) is a new technology emerging on the basis of MIT, and the materials produced using this technique are called ion-imprinted polymers (IIPs) [ 19 ]. As a branch of MIT, IIT has been regarded as a promising method for synthesizing materials owing to its capacity for realizing ion recognition with high specificity and selectivity [ 20 ].…”

“…Moreover, the memory effect generated during the preparation of IIPs has ensured the recognition of the target metal ions with high selectivity [ 21 , 27 ]. In a word, combining the advantages of electrochemical sensors such as high sensitivity, low cost and easy miniaturization, IIECSs constructed with IIPs as the sensitive material of electrochemical sensor not only has the advantages of simple preparation process and easy operation, but also has better selectivity, sensitivity and stability than the conventional ECSs [ 19 ].…”

Heavy metal ions (HMIs) pose a serious threat to the environment and human body because they are toxic and non-biodegradable and widely exist in environmental ecosystems. It is necessary to develop a rapid, sensitive and convenient method for HMIs detection to provide a strong guarantee for ecology and human health. Ion-imprinted electrochemical sensors (IIECSs) based on nanomaterials have been regarded as an excellent technology because of the good selectivity, the advantages of fast detection speed, low cost, and portability. Electrode surfaces modified with nanomaterials can obtain excellent nano-effects, such as size effect, macroscopic quantum tunneling effect and surface effect, which greatly improve its surface area and conductivity, so as to improve the detection sensitivity and reduce the detection limit of the sensor. Hence, the present review focused on the fundamentals and the synthetic strategies of ion-imprinted polymers (IIPs) and IIECSs for HMIs detection, as well as the applications of various nanomaterials as modifiers and sensitizers in the construction of HMIIECSs and the influence on the sensing performance of the fabricated sensors. Finally, the potential challenges and outlook on the future development of the HMIIECSs technology were also highlighted. By means of the points presented in this review, we hope to provide some help in further developing the preparation methods of high-performance HMIIECSs and expanding their potential applications.

Sustainable management of spent lithium-ion batteries, LIBs, is an urgent and critical challenge due to the number of such devices reaching the end-of-life. Recycling can offer a path for the recovery of valuable raw materials such as lithium and cobalt, whose supply is critical. Thus, it is mandatory to develop efficient ways for the selective recovery of Li and Co from the cathode degradation processes. In this study the most updated organic acids-based processes for the degradation of LiCoO 2 , the most common LIBs cathode, is explored to obtain a leached solution containing Li and Co. The possibility to exploit the 3-methyl-1-octylimidazolium thenoyltrifluoroacetone, Omim-TTA, ionic liquid was demonstrated to efficiently separate Li and Co. In particular it was possible to recover > 70 % of Li and separate it from Co using this ionic liquid, independently from the organic acid used for the leaching procedure and adding EDTA to the aqueous phase. The quantification was carried out through ICP analysis; the recovering of the unaltered ionic liquid was also demonstrated, to further increase the global sustainability of the process.
