“…Dye degradation is an indispensable part when using dyes for applications, and this phenomenon has attracted the attention of most dye researchers. Chromatography has been the most effective technique for separation dye mixtures, and it has been widely applied for characterizing dye degradation products [20,36–39]. According to Sinha et al., HPLC chromatography can help to observe the decolorization process, since the shift of major peak and the appearance of a new peak can be seen from the HPLC chromatogram, indicating the discoloration of dye into different intermediates [38].…”

Dyes have become common substances since they are employed in mostly all objects surrounding our daily activities such as clothing and upholstery. Based on the usage and disposal of these objects, the transfer of the dyes to other media such as soil and water increases their prevalence in our environment. However, this prevalence could help to solve crimes and pollution problems if detection techniques are proper. For that reason, the detection and characterization of dyes in complex matrices is important to determine the possible events leading to their deposition (natural degradation, attempts of removal, possible match with evidence, among others).Currently, there are several chromatographic and mass spectrometric approaches used for the identification of these organic molecules and their derivatives with high specificity and accuracy. This review presents current chromatographic and mass spectrometric methods that are used for the detection and characterization of disperse, acid, basic, and reactive dyes, and their derivatives.

“…In addition, dopant dislodgments from reacted nanoparticles and islet encapsulations by the passivated layer often block the benefits of surface modification, − leading to the loss of reactivity or a trade-off of reactivity–selectivity. It should be noted that surface modification could form a new crystal structure (e.g., FeS and Fe 3 C) on the surface of nFe 0 in some cases. − However, the surface modification could not change the electronic structure of the main Fe 0 body-centered cubic (BCC) structure, such as Fe–Fe bond length and Fe coordination environment of the nFe 0 body, which could be changed by lattice engineering as described below.…”

Lattice engineering of nanomaterials holds promise in simultaneously regulating their geometric and electronic effects to promote their performance. However, local microenvironment engineering of Fe 0 nanoparticles (nFe 0 ) for efficient and selective environmental remediation is still in its infancy and lacks deep understanding. Here, we present the design principles and characterization techniques of lattice-doped nFe 0 from the point of view of microenvironment chemistry at both atomic and elemental levels, revealing their crystalline structure, electronic effects, and physicochemical properties. We summarize the current knowledge about the impacts of doping nonmetal p-block elements, transitionmetal d-block elements, and hybrid elements into nFe 0 crystals on their local coordination environment, which largely determines their structure−property−activity relationships. The materials' reactivity−selectivity trade-off can be altered via facile and feasible approaches, e.g., controlling doping elements' amounts, types, and speciation. We also discuss the remaining challenges and future outlooks of using lattice-doped nFe 0 materials in real applications. This perspective provides an intuitive interpretation for the rational design of lattice-doped nFe 0 , which is conducive to real practice for efficient and selective environmental remediation.
