Adsorption Selectivity

Three Co(ii)-MOFs have been synthesized. The desolvated frameworks of 2 and 3 exhibit good adsorption selectivity for C2H2 and CO2 over CH4 at 273 and 298 K. Moreover, 1–3 show that there exist antiferromagnetic interactions between metal ions.

Paramagnetic Metal

The syntheses, structures and magnetic properties of giant molecular 3d and 3d/4f paramagnetic metal clusters are surveyed. Such complexes combine fascinating crystal structures, interesting magnetic properties and sizes comparable to those of classical magnetic nanoparticles providing a powerful bottom-up approach to nanoscale magnetic materials.

Kinetics Of

A type of cross-linking starch microsphere (CSMs) has been synthesized via reversed phase suspension method. Crosslinked starch microsphere has good adsorption performance to metal ions in water. The adsorption kinetics of Co (II) on the CSMs, selectivity of adsorption CSMs towards Co (II),Cu (II),Pb (II),Cd (II) and adsorption effects of media towards Co (II) were investigated. The CSMs and its adsorption product were comparatively characterized by X-ray diffraction (XRD). The results showed that The adsorption rate is mainly controlled by liquid film diffusion, and the constant of adsorption rate is 0.0686min-1 at 308K. The crystal structure of the CSMs decreased greatly after the incorporation of Co (II). Co (II) has better adsorption selectivity on CSMs. Ions coexist and other substances in the solution have certain impact on adsorption. Those data are helpful for treatment of the wastewater containing heavy ions.
