TL;DR: Morin-APSG was found to be highly stable in common organic solvents, acidic medium or alkaline medium up to pH 8.8 and successfully employed in the separation and preconcentration of the investigated precious metal ions from some spiking water samples.

TL;DR: HEPTS and its Cu(II) complexes showed high activity against gram negative bacteria and the room temperature solid state ESR spectra of the complexes show an axial spectrum with dx2-y2 ground state, suggesting distorted tetragonal geometry around Cu( II) center.

TL;DR: In this paper, a mesoporous silica nanoparticles with dibenzoylmethane was used for the removal of Cu(II), Hg(II) and Cd(II).
Abstract: In this paper, a novel composite was synthesized through the modification of mesoporous silica nanoparticles with dibenzoylmethane and used for the removal of Cu(II), Hg(II), and Cd(II) ions from aqueous media. The structure of the novel composite was identified using FT-IR, XRD, CHN, and SEM techniques. Kinetic studies elucidated the relevance of the pseudo-second-order model for the removal of Cd(II) ions while the pseudo-first-order controlled the removal of Cu(II) or Hg(II) ions. Also, equilibrium studies elucidated that the removal of Cd(II), Hg(II), or Cu(II) ions followed the Langmuir isotherm. The synthesized composite possesses maximum adsorption capacity equals 35.37, 25.17, and 31.76 mg g−1 in the case of Cd(II), Hg(II), and Cu(II) ions, respectively. The removal processes were chemisorption in nature and the % desorption of Cd(II), Hg(II), and Cu(II) ions was 99.12, 99.07, and 98.37%, respectively using 0.5 V/V% HCl: water as eluting media. The regeneration of the composite is judged by noticing the % removal of metal ions or the adsorption capacity which remained almost constant after five regeneration cycles.

TL;DR: The correlation results suggested that the pseudo-second-order model was the best choice among all the kinetic models to describe the adsorption behavior of Au(III), Pt(IV) and Pd(II) onto GMCCR.
