“…The FT-IR spectra of the ferric chloride hexahydrate (FC) before and after reaction with 0.1/0.9 (mg/L), 0.5/0.5 (mg/L) and 0.9/0.1 (mg/L) antimony solutions were investigated ( Figure 5). The bands that appeared at approximately~3249 cm −1 were assigned to the strong O-H stretching vibrations [46]. The small peaks that appeared at~2346 cm −1 were attributed to some impurities, since FC used in this study was 99% pure.…”

Coagulation and precipitation appear to be the most efficient and economical methods for the removal of antimony from aqueous solution. In this study, antimony removal from synthetic water and Fe solubility with ferric chloride (FC) coagulation has been investigated. The effects of pH, FC dosage, initial antimony loading and mixed Sb(III), Sb(V) proportions on Fe solubility and antimony removal were studied. The results showed that the Sb(III) removal efficiency increased with the increase of solution pH particularly due to an increase in Fe precipitation. The Sb(V) removal was influenced by the solution pH due to a change in Fe solubility. However, the Fe solubility was only impaired by the Sb(III) species at optimum pH 7. The removal efficiencies of both Sb species were enhanced with an increase in FC dose. The quantitative analysis of the isotherm study revealed the strong adsorption potential of Sb(III) on Fe precipitates as compared to Sb(V). Furthermore, the removal behavior of antimony was inhibited in mixed proportion with high Sb(V) fraction. In conclusion, this study contributes to better understanding the fate of Sb species, their mobilities, and comparative removal behavior, with implications for Fe solubility using ferric chloride in different aqueous environments.

“…The ground state in some of the transitioning particles becomes more polar than the excited state. (Santos et al, 2015). There is a shift in the maximum wavelength towards the smaller or hypochromic (blue shift) spectrum of Fe 3+ (260.00 nm) from the FeCl3.6H2O solution to the Fe 3+ spectrum from Bis-(4-(tert-butyl)-N-(methylcarbamothioyl)benzamide) Iron (III) solution.…”

“…Based on the theory, the metal vibration absorption with an O group of the ligands will appear at a wavenumber of 600-400 cm -1 . The Fe-O vibration absorption analysis result of the complex compound Bis-(4-(Tert-Butyl)-N-(Methylcarbamothioyl)Benzamide)-Iron (III) appeared in the 478.2 cm -1 and 588 cm -1 , and The Fe-N vibration absorption analysis result of the complex compound Bis-(4-(Tert-Butyl)-N-(Methylcarbamothioyl)Benzamide)-Iron (III) appeared in the 356.5 cm -1 (Rao and Venkataraghavan, 1962;Santos et al, 2015;Saratovskikh et al, 2013;Wang and Andrews, 2006).…”

Thiourea derivatives were much used in drug discovery and drug-making, such as for an anticancer. The formation of drug complexes can increase lipophilicity through chelation formation, and the drug action is significantly upward due to the effective permeability to the center. In another study, the alteration of the compound becomes the complex with metal will grow in its activity so recently we have synthesized the Bis-(4-(Tert-Butyl)-N-(Methylcarbamothioyl) Benzamide)-Iron (III) complex. The synthesis of Fe (III) metal with the 4-(Tert-Butyl)-N-(Methylcarbamothioyl) Benzamide in ethanol by reflux at 75 o C for 7 hours. Hot Stage Microscopy, UV-Visible Spectrophotometry Infrared Spectrophotometry, and Massa Spectrophotometry were used to characterize the complex. This study concerns representing, inferring, and predicting pharmacokinetics and toxicity and molecular docking complexes. The complex weight was 0.29469 g. Its purity has been tested using the melting point determination and has obtained its range was 113 o -115 o C. The Characteristics of Bis-(4-(Tert-Butyl)-N-(Methylcarbamothioyl) Benzamide)-Iron(III) complex have a maximum wavelength of 260 nm and provide absorption of Fe-O vibrations at wavenumbers 478.2 cm -1 and 588 cm -1 , and the m/z complex of spectrophotometry mass was 559.31. The molecular docking process was performed using AutodockTools-1.5.6 software. It showed that Bis-(4-(Tert-Butyl)-N-(Methylcarbamo-thioyl)Benzamide)-Iron(III) complex could interact with ribonucleotide reductase enzyme, and it has better interaction than the 4-(Tert-Butyl)-N-(Methylcarbamothioyl)Benzamide with the binding affinity energy (ΔG)of -8.52 kcal/mole and the constant inhibition (Ki ) of 568.55 nM.

“…Due to the high reactivity of tannins, they are prone to interact with other molecules, and hence recently multicomponent materials, partly made of the sustainable tannin, have evoked increased interest. More precisely, in the last two decades, tannin-derived hybrid materials are an emerging field, as they feature new perspectives due to combined or enhanced materials’ properties and hence allow an expansion of the materials’ application scope [ 28 , 29 ]. In particular, the interaction of inorganic and organic materials, in order to generate new materials with favorable properties of each organic and inorganics, is discussed [ 29 , 30 ].…”

Tannin-Based Hybrid Materials and Their Applications: A Review

et al. 2020

Tannins are eco-friendly, bio-sourced, natural, and highly reactive polyphenols. In the past decades, the understanding of their versatile properties has grown substantially alongside a continuously broadening of the tannins’ application scope. In particular, recently, tannins have been increasingly investigated for their interaction with other species in order to obtain tannin-based hybrid systems that feature advanced and/or novel properties. Furthermore, in virtue of the tannins’ chemistry and their high reactivity, they either physicochemically or physically interact with a wide variety of different compounds, including metals and ceramics, as well as a number of organic species. Such hybrid or hybrid-like systems allow the preparation of various advanced nanomaterials, featuring improved performances compared to the current ones. Consequently, these diverse-shaped materials have potential use in wastewater treatment or catalysis, as well as in some novel fields such as UV-shielding, functional food packaging, and biomedicine. Since these kinds of tannin-based hybrids represent an emerging field, thus far no comprehensive overview concerning their potential as functional chemical building blocks is available. Hence, this review aims to provide a structured summary of the current state of research regarding tannin-based hybrids, detailed findings on the chemical mechanisms as well as their fields of application.
