The present study deals with the carrier-facilitated transport of manganese from this acidic leach solution in the ELM system. The ELM consists of MDEHPA as the extractant, industrial solvent as the inert diluent; non-ionic polyethylene glycol as a surfactant and sulfuric acid as the stripping solution. The main parameters influential affecting the ELM stability and extraction of manganese are the pH of the acidic leach solution, mixing speed, concentration of the stripping solution, extractant and surfactant, phase ratio and treatment ratio. With respect to the parameters mentioned, the optimum conditions for the process were determined. The results demonstrated the possibility of 93% extraction of manganese by ELM from the acidic leach solutions at optimum operational conditions.

“…In addition to mixing speed, extractant, and surfactant concentration, another parameter is the type of stripping agent. 26 The selection of a suitable stripping solution is considered to be one of the key factors for an effective ELM system. Initially we examined HCl, H 2 SO 4 , and HNO 3 as stripping solutions for the current ELM.…”

“…Recently, attention has focused on application of liquid-liquid extraction to the removal and preconcentration of toxic metal ions for environmental protection. [2][3][4][5] The extractant plays an important role in determining the efficiency of the extraction and separation processes. Thus, the development of novel extractants, which perform better than conventional commercial extractants, is required for effective removal of toxic metal ions.…”

“…Mixtures of extractants have been employed by different investigators to extract Ni 2+ , Co 2+ , Pb 2+ and Cd 2+ at relatively low pH (1-3) [46][47][48], however, there are few single extractants that can extract metal ions efficiently at lower pH values. Most extractants are used commercially and are not effective for the recovery of these metals in a highly acidic medium (pH < 4) [45,46,[49][50][51][52][53][54][55]. 2-(diphenylphosphino)aminopyridine showed good efficiency and affinity for metal ions at pH 2 according to the results obtained, making it suitable for solvent extractions in acidic media.…”

The solvent extraction of metal picrates such as Ni2+, Cu2+, Co2+, Pb2+ and Cd2+ from the aqueous to the organic phase was studied using 2-(diphenylphosphino)aminopyridine (Ph2PNHpy). The effects of parameters including the pH of the aqueous phase and the ligand solution volume were investigated to determine the extraction ability of the ligand for metal ions. The results showed that the extraction percentages of metal ions were high at low pH values. The antibacterial activity of the aminophosphine was also screened against Escherichia coli (E. coli) ATCC 25922, Staphylococcus aureus (S. aureus) ATCC 25923, Pseudomonas syringae pv. tomato (P. syringae) DC300, Salmonella enterica serotype Typhmurium (S. typhmurium) SL 1344 and Streptococcus mutans (S. mutans) ATCC 25175. From the studies of antibacterial activity, it was observed that the ligand exhibited a potent inhibitory effect against all Gram-negative and Gram-positive bacteria with a diameter of inhibition zone ranging from 3.86 to 18.10 mm. The aminophosphine ligand (Ph2PNHpy) should be considered as a suitable bio-active molecule for antimicrobial material design and next-generation, non-toxic drug fabrication. The Ph2PNHpy obtained may have the potential for use as an antimicrobial additive for bioengineering applications.
