“…Emerging as a potential alternative to traditional solvent extraction, separation based on polymer inclusion membranes (PIMs), consisting of a base-polymer, carrier (extractant) and plasticizer or modifier in some cases, has been attracting increased attention in recent years [1]. The main reason behind this trend is based on the better stability of PIMs than supported liquid membranes (SLMs) which are the most frequently used liquid membranes at present [1][2][3][4][5][6][7][8][9][10]. Despite the better stability of PIMs [1,11], their robustness is still considered insufficient for applications on an industrial scale.…”

“…Their advantages and disadvantages are summarized in Table 3. Various metal ions from common metals (copper, nickel, and cobalt) [97] and valuable metals (platinum, gold) [98,99] to radioactive species (uranium) [100] have been extracted using LM techniques. As noted in Table 3, there are several concerns regarding membrane stability when organic solvents are used.…”

The demand for the recovery of valuable metals and the need to understand the impact of heavy metals in the environment on human and aquatic life has led to the development of new methods for the extraction, recovery, and analysis of metal ions. With special emphasis on environmentally friendly approaches, efforts have been made to consider strategies that minimize the use of organic solvents, apply micromethodology, limit waste, reduce costs, are safe, and utilize benign or reusable materials. This review discusses recent developments in liquid- and solid-phase extraction techniques. Liquid-based methods include advances in the application of aqueous two- and three-phase systems, liquid membranes, and cloud point extraction. Recent progress in exploiting new sorbent materials for solid-phase extraction (SPE), solid-phase microextraction (SPME), and bulk extractions will also be discussed.

“…Parhi and Sarangi 16 have separated copper, zinc, cobalt, and nickel with the help of different carriers such as LIX 841, TOPS-99, and Cyanex 272. Duan et al 15 have used a new sandwich SLM (i.e., two-membrane-three-compartment cell) to separate copper, nickel, and cobalt from its ammoniacal solution. They have used H 2 SO 4 as a stripping solution in two stripping compartments with different concentrations and Acorga M5640 in kerosene as a liquid membrane.…”

“…are there for separation of heavy metals. − However, they have their own set of merits and limitations. In recent times, the supported liquid membrane (henceforth abbreviated as SLM) process has received increased attention from the research community for separation of heavy metals. − This research group is also actively working on separation of heavy metal through SLM.…”

A new type of supported liquid membrane setup has been developed in this work. The setup consist of an in situ electrodeposition unit in strip phase which helps “stripped” nickel and zinc from synthetic wastewater get electrodeposited on the cathode surface. This type of separation technique not only helps to separate toxic heavy metals from wastewater but also yields an useful end product in the form of electroplated material. Two types of carrier, i.e., trioctyl amine and di-(2-ethylhexyl)phosphoric acid, have been used in the organic phase to separate zinc and nickel. The separation has been done individually as well as in a condition of binary pollutant in the feed phase. Various physicochemical parameters have been optimized to maximize the transport and deposition of metals on the cathode surface. Face-centered central composite designs in response to surface methodology have been performed on varied ratios of binary pollutant and their carriers in order to obtain optimum performance of the separation unit.
