Abstract: An increase in the pollutants such as hazardous refractory contaminations, organic dyes, pharmaceutical and pesticide contaminants which are widely disposed to water resources due to population and global industrialization is becoming one of the most significant health issues in the world. Due to the unique properties, easy production, low-cost preparation, and excellent degradation of water and wastewater pollutants, magnetic-MXene nanocomposites are promising candidates with many attractive characteristics. These composites offer new fascinating perspectives in various applications such as biosensors, cancer theragnostic, imaging strategies, and especially in water treatment. This paper reviews magnetic-MXene nanocomposites for removing contaminants from aqueous environments. The concept of using magnetic nanomaterials for water treatment, MXene applications and implications for the degradation of water and wastewater pollutants, and magnetic-MXene nanocomposites for water treatment will be discussed. Future trends on MXene and Magnetic-MXene nanomaterials for water treatment and environmental applications will also be explained. • Pollutants removal by magnetic-MXene-based nanocomposites was reviewed. • Magnetization of nanocomposites of MXene enhanced pollutants degradation. • Magnetization of nanocomposites of MXene enhanced antibacterial properties. • A future perspective was developed.

TL;DR: In this article , a review of the latest suggested adsorption mechanisms, kinetics, and isotherms of MOFs-based materials for removing cadmium ions is presented.
Abstract: Various articles have been written about MOFs, which are organic-inorganic polymer structures that are unique in three-dimensional porosity, crystalline structure, and their ability to adsorb cadmium ion pollutants from aqueous solutions. These materials possess active metal sites, highly porous structures, high specific surfaces, high chemical functionality, and porous topologies. It is necessary to study adsorption kinetics, isotherms, and mechanisms in order to better understand the adsorption process. Adsorption kinetics can provide information about the adsorption rate and reaction pathway of adsorbents. Adsorption isotherms analyze the possibility of absorbances based on the Gibbs equation and thermodynamic theories. Moreover, in practical applications, knowledge of the adsorption mechanism is essential for predicting adsorption reactions and designing MOFs structures. In this review, the latest suggested adsorption mechanisms, kinetics, and isotherms of MOFs-based materials for removing cadmium ions are presented. A comparison is then conducted between different MOFs and the mechanisms of cadmium ion removal. We also discuss the future role of MOFs in removing environmental contaminants. Lastly, we discuss the gap in research and limitations of MOFs as adsorbents in actual applications, and probable technology development for the development of cost-efficient and sustainable MOFs for metal ion removal.

TL;DR: A highly sensitive electrocatalytic sensor designed and fabricated by the incorporation of NiO dope Pt nanostructure hybrid (NiO–Pt–H) showed an excellent catalytic activity and was used as a powerful tool for the determination of cysteamine in the presence of serotonin.
Abstract: A highly sensitive electrocatalytic sensor was designed and fabricated by the incorporation of NiO dope Pt nanostructure hybrid (NiO–Pt–H) as conductive mediator, bis (1,10 phenanthroline) (1,10-phenanthroline-5,6-dione) nickel(II) hexafluorophosphate (B,1,10,P,1,10, PDNiPF6), and electrocatalyst into carbon paste electrode (CPE) matrix for the determination of cysteamine. The NiO–Pt–H was synthesized by one-pot synthesis strategy and characterized by XRD, elemental mapping analysis (MAP), and FESEM methods. The characterization data, which confirmed good purity and spherical shape with a diameter of ⁓ 30.64 nm for the synthesized NiO–Pt–H. NiO–Pt–H/B,1,10, P,1,10, PDNiPF6/CPE, showed an excellent catalytic activity and was used as a powerful tool for the determination of cysteamine in the presence of serotonin. The NiO–Pt–H/B,1,10, P,1,10, PDNiPF6/CPE was able to solve the overlap problem of the two drug signals and was used for the determination of cysteamine and serotonin in concentration ranges of 0.003–200 µM and 0.5–260 µM with detection limits of 0.5 nM and 0.1 µM, using square wave voltammetric method, respectively. The NiO–Pt–H/B,1,10,P,1,10,PDNiPF6/CPE showed a high-performance ability for the determination of cysteamine and serotonin in the drug and pharmaceutical serum samples with the recovery data of 98.1–103.06%.
