“…The functionalization process was achieved through the atom transfer radical polymerization (ATRP) technique, resulting in spherical nanoparticles with a magnetic core and an average size of approximately 30 nm. The researchers found that the adsorption capacity of the functionalized nanoparticles was unaffected by the pH range studied (pH = 3 to pH = 9), and the adsorption efficiency for both dyes was 100% [ 152 ]. These studies demonstrate that the functionalization of nanoparticles with positively charged polymers enhances the adsorption efficiency of anionic dyes by facilitating interactions with their negative charges.…”

Due to the ever-growing global population, it is necessary to develop highly effective processes that minimize the impact of human activities and consumption on the environment. The levels of organic and inorganic contaminants have rapidly increased in recent years, posing a threat to ecosystems. Removing these toxic pollutants from the environment is a challenging task that requires physical, chemical, and biological methods. An effective solution involves the use of novel engineered materials, such as silica-based nanostructured materials, which exhibit a high removal capacity for various pollutants. The starting materials are also thermally and mechanically stable, allowing for easy design and development at the nanoscale through versatile functionalization procedures, enabling their effective use in pollutant capture. However, improvements concerning mechanical properties or applicability for repeated cycles may be required to refine their structural features. This review focuses on hybrid/composite polymer-silica nanostructured materials. The state of the art in nanomaterial synthesis, different techniques of functionalization, and polymer grafting are described. Furthermore, it explores the application of polymer-modified nanostructured materials for the capture of heavy metals, dyes, hydrocarbons and petroleum derivatives, drugs, and other organic compounds. The paper concludes by offering recommendations for future research aimed at advancing the application of polymer-silica nanostructured materials in the efficiency of pollutant uptake.

In this study, a polymer brush derived from poly(2-(tert-butylamino)ethyl methacrylate)-coated mesoporous silica nanoparticles (PTBAEMA–SO3H@MSNPs) was successfully fabricated. The structure and morphology of PTBAEMA–SO3H@MSNPs were studied using transmission electron microscopy, Fourier-transform infrared spectroscopy, dynamic light scattering, and elemental analysis techniques. The optimal conditions for the removal of rhodamine B (Rh B) and crystal violet (CV) by PTBAEMA–SO3H@MSNPs were determined. The best adsorption efficiency was found at an Rh B concentration of 150 ppm, adsorbent amount of 10 mg, contact time of 40 min, and pH 5 and at a CV concentration of 350 ppm, contact time of 40 min, and pH 9. The adsorption equilibrium was fitted with the Langmuir, Freundlich, Temkin, and Redlich–Peterson isotherm models in both linear and nonlinear forms. Equilibrium data were best fitted with the Langmuir model, with maximum adsorption capacities of 147.78 and 343.57 mg g–1 for Rh B and CV, respectively. The adsorption of both dyes onto the PTBAEMA–SO3H@MSNP adsorbent occurred spontaneously in an exothermic manner and with increased randomness. The adsorption of Rh B and CV onto the PTBAEMA–SO3H@MSNP adsorbent followed pseudo-second-order kinetics. The findings of this study indicate that PTBAEMA–SO3H@MSNPs are highly effective in removing Rh B and CV from water samples.

The main objective of this study was to optimize the adsorption process of methylene blue on a natural, low-cost adsorbent, Leonurus cardiaca L. biomass powder, in order to maximize dye removal efficiency from aqueous solutions. For this purpose, the Taguchi method was used based on an L27 orthogonal array design considering six controllable factors at three levels. The percentage contribution of each factor was computed using analysis of variance (ANOVA). The optimal adsorption conditions were established. The experimental data from equilibrium and kinetic studies were modelled using specific equilibrium isotherms and kinetic models. Thermodynamic parameters were calculated in order to determine the main adsorption mechanism. The obtained results showed that the ionic strength is the factor that most influences dye adsorption (percentage contribution 72.33%), whereas the adsorbent dose had the least impact. The Sips isotherm and the general kinetic model most accurately characterized the process. The maximum adsorption capacity 103.21 (mg g−1) indicated by the Sips isotherm and the equilibrium time (40 min) were better compared to the values obtained for other bio-adsorbents used for methylene blue adsorption. The main mechanism involved in the adsorption is physisorption, while chemisorption only contributes marginally to the process.
