This review article gives an insight into recent developments in chelating agents modified nanostructures in metal extraction and catalysis. The ability of functionalization by anchoring specific functional groups on the surface of nanostructures makes it possible to synthesize different types of desired chelated nanostructures for their use as catalysts and metal ion scavengers. Keeping these aspects in outlook this review emphasizes mainly on the synthesis of chelating agent functionalized nanostructures and their applications in the field of metal ion extraction and catalysis. The review article provides comprehensive information about the work that has been done in the past 5 years in the field of metal ion extraction and catalysis using chelating agent modified nanoparticles.

“…During the process, which lasts about 5 hours, the effluent flows continuously and stored in a tank before being discharged. Sampling is made by using polypropylene bottles of 250 mL and 1 L, washed and rinsed beforehand with distilled water [26,27]. For each sample, the scoop is immersed in the tank about 25 cm deep to collect a sample of 250 mL.…”

“…The witness sample was collected in a 1 liter bottle from the tap of the tank containing water of the unit which is deserves to domestic use and formulation. The bottles are labeled and stored at 4 ° C in a ice box, then transported to the laboratory within 24 hours for analysis [26,27]. The samples which were used for the determination of TME were treated with nitric acid ((HNO3, 10%) as soon as collected up to pH = 1.5 to ensure good conservation of the constituents [26,27].…”

In this study, the concentrations (mg / L) of trace metal elements (TME) in an effluent from an industrial soap and cosmetic unit (SCI11) were evaluated. Four (4) composite samples and a witness sample (1) were collected. Nine (9) physicochemical parameters (T, pH, EH, SS, Al, Cr, Fe, Pb, and Zn) were analyzed according to AFNOR standards.The results showed that these effluents are characterized by high mean concentrations of suspended solids (266.75 ± 147.20 mg / L and Cr (0.678 ± 0.068 mg / L) which are far beyond the reference values of the Service Inspection of Classified Installations (SIIC). On the other hand, the mean concentrations of TME Fe, Al, Zn, respectively at 0.585 ± 0.03 mg / L, 0.618 ± 0.030 mg / L, and 0.244 ± 0.015 mg / L are in agreement with the SIIC reference values. The study also found that the effluent is behaving like a reducer with a mean EH redox potential of (-13 ± 1.87 mV). Mean values of pH (6.67 ± 0.60) and temperature T (29.58 ± 0.82 ° C) are in the order of the values recommended by the SIIC. Overall, the PCA analysis has shown that this effluent is a source of TME pollution and physical SS pollution.

“…The pH of was the most important factor for metal-chelate formation. [32][33][34][35] High recoveries were obtained at the pH 8.0 (experiments 4). At the low pH level (−),48.5% recovery for Cd(II) and 51.1% for Pb(II) were achieved (experiment 7).…”

Single solidified floating organic drop microextraction was used for the preconcentration and determination of Cd(II) and Pb(II). The procedure employed 1-(2-pyridylazo)-2-naphthol as a chelating agent, 1-undecanol as the extractant solvent, and methanol was as the dispersive solvent. Factors influencing the recovery of Cd(II) and Pb(II) such as the pH, volume of extractant, volume of ligand, volume of dispersant, and stirring time were optimized by Plackett Burman design. In order to complete the optimization, a central 2 3 +star orthogonal composite design was applied. The limits of detection for Cd(II) and Pb(II) were 0.15 and 0.52 µg L -1 . The validation of procedure was evaluated by the analysis of TMDA 70 Fortified Water and NCSDC-73349 Bush Branches certified reference materials. The determined values were in good agreement with the certified values. The single solidified floating organic drop microextraction method was employed for the determination of cadmium and lead in water, vegetables, and fruit.
