Silica-incorporated molecularly imprinted polymers for removal of acid black ATT via solid-phase extraction
Silica-incorporated molecular imprinted polymer (SiO2@MIP) was synthesized via bulk polymerization using methacrylic acid (MAA) as a functional monomer and acid black ATT as the template molecule, while the corresponding non-imprinted polymer (SiO2@NIP) was prepared in the absence of the template. The polymer was characterized via SEM, FTIR, EDX, and XRD. The effect of contact time, pH, temperature, and initial dye concentration was optimized. The adsorption mechanism followed the pseudo-second order kinetic (K2 = 0.0028 mg g−1) model. The values of (∆H˚ = −12.7486 kJ/mol), and (∆S˚ = − 12.749 J/mol) suggested that the adsorption of acid black ATT is a spontaneous exothermic process. The MIP was evaluated as the solid phase extraction media with very good results owing to its striking features such as mechanical strength, selective adsorption with very high recyclability for the acid black ATT, ease of handling, and cost effectiveness contributing to green chemistry. The silica-incorporated MIP polymer networking proved very effective in the overall adsorption characteristics of the resultant material. The resultant MIP was applied for the removal of dyes from spiked water samples (tap water, river water, and distilled water) with adsorption higher than 90%.
期刊介绍：
The objective of the Journal of Nanoparticle Research is to disseminate knowledge of the physical, chemical and biological phenomena and processes in structures that have at least one lengthscale ranging from molecular to approximately 100 nm (or submicron in some situations), and exhibit improved and novel properties that are a direct result of their small size.
Nanoparticle research is a key component of nanoscience, nanoengineering and nanotechnology.
The focus of the Journal is on the specific concepts, properties, phenomena, and processes related to particles, tubes, layers, macromolecules, clusters and other finite structures of the nanoscale size range. Synthesis, assembly, transport, reactivity, and stability of such structures are considered. Development of in-situ and ex-situ instrumentation for characterization of nanoparticles and their interfaces should be based on new principles for probing properties and phenomena not well understood at the nanometer scale. Modeling and simulation may include atom-based quantum mechanics; molecular dynamics; single-particle, multi-body and continuum based models; fractals; other methods suitable for modeling particle synthesis, assembling and interaction processes. Realization and application of systems, structures and devices with novel functions obtained via precursor nanoparticles is emphasized. Approaches may include gas-, liquid-, solid-, and vacuum-based processes, size reduction, chemical- and bio-self assembly. Contributions include utilization of nanoparticle systems for enhancing a phenomenon or process and particle assembling into hierarchical structures, as well as formulation and the administration of drugs. Synergistic approaches originating from different disciplines and technologies, and interaction between the research providers and users in this field, are encouraged.
