“…Consequently, the subsequent diffusion of species into the strip solution does not depend on the acid concentration at the concentration above 0.5 mol/L. [49] Figure 7b reveals the effect of HCl in the strip solution on the transport efficiency of other metals existing in the feed solution. As seen in this figure, the transport efficiency of nickel and cadmium increased with increasing the HCl concentration, whereas the transport efficiency of zinc initially descended, and then increased with the further enhancement of HCl.…”

Non-dispersive selective extraction of Ge(IV) tartrates was carried out from simulated fly ash solutions containing heavy metals through supported liquid membranes (SLM). The optimum transport was obtained using a PTFE membrane containing Alamine 336 5%v/v in the condition of tartaric acid 2.76 mmol/L and HCl 1 mol/L in feed and strip phases, respectively. Under this condition, a hollow fiber (HF) SLM experiment was conducted. The results showed that this system could transport germanium from the feed to the strip phase so much faster than the flat sheet (FS) SLM system. The rate of transport through HFSLMs is comparable to dispersive extractions.

“…Consequently, the proton concentration gradient in the stripping phase does not create an important driving force during the transport of germanium. (Duan et al, 2017) According to the literature, this behavior occurs because the driving force saturation for the diffusion across the membrane takes place when metal compound concentrations enhance at the interfacial level in the membrane-strip solution interface. (Venkateswaran and Palanivelu, 2005) Moreover, the effect of HCl on the transport of heavy metals in the feed solution showed that the transport of these metals is not significant in comparison to germanium transport because the transport efficiencies of all these metals were less than 0.5%.…”

Germanium can be found in industrial leachates of coal gasification fly ashes or zinc plant residues, containing various heavy metals. In this research, the selective separation of germanium from simulated water coal gasification fly ash leach liquors containing Zn(II), Ni(II), Cd(II), and Co(II) through the flat sheet and hollow fiber supported ionic liquid membrane (FSSLM & HFSLM) systems was developed using an ionic liquid Aliquat 336 as a carrier. As a result, Aliquat-336 was a very fast and effective carrier for the selective transport from these types of solutions. The selective transport of germanium through the mentioned FSSLM system was carried out from a simulated zinc acidic leach liquor containing the aforementioned metals and 0.5 mol/L of H 2 SO 4 under the condition found for the neutral solutions. As a result, an insignificant difference was observed between the germanium transports from both solutions.The germanium transport from both types of solutions was selective and its efficiency reached >98%. Finally, a facilitated transport of germanium was conducted in an HFSLM under the same condition obtained for the FSSLM system. It was observed that this system could transport major amounts of germanium species in the first 30 min showing faster transport than the FSSLM system.

“…Ni 2+ exposition can cause poisonous effects for example asthma, contact allergy, dermatitis, gastrointestinal distress, cancer (lung, oral cavity, and larynx), kidney & sinus problem, promotion of disorders in CNS, and pulmonary fibrosis. HMI can be easily absorbed by animals and plants, and then may mount up in the human body by way of food chain . Owing to the dangerous consequence of HMI, it is very imperative and important to discover advantageous, efficient, and practicable technique to treat wastewater containing poisonous metal pollutants, and remove their dangerous effects on ecology and human health.…”

(E)‐N’‐Chlorobenzylidene‐4‐methylbenzenesulfonohydrazide (CBMBSH) compounds were synthesized using a simple condensation process from the derivatives of chlorobenzaldehyde and 4‐methylbenzenesulfonylhydrazine in a good yield which crystallized in ethanol. The CBMBSH molecules were totally characterized using conventional spectroscopic techniques such as 1H‐NMR, 13C‐NMR, FTIR, and UV‐Vis spectroscopy. The molecular structures of the CBMBSH molecules were confirmed using a single crystal X‐ray diffraction (SCXRD) method and used for the potential detection of heavy metal ion, nickel (Ni2+) using a reliable I−V technique. A thin layer of CBMBSH was deposited onto a flat glassy carbon electrode (GCE) with 5 % nafion coating binder in order to modify a sensitive and selective Ni2+ ionic sensor. Sensitivity, limit of detection (LOD), and limit of quantification (LOQ) of the modified electrode towards Ni2+ were calculated from the slope of calibration curve as 949.0 pAμM−1cm−2, 98.0±2.0 pM, and 326.67 mM respectively. The approaching CBMBSH/GCE sensor was applied to the selective determination of Ni2+ in spiked real samples, and found satisfactory and rational results.
