Abstract:
Antibiotic residues in wastewater have attracted great attention for their potential toxicity to environment. In this work, a zirconium-based metal-organic framework (PCN-777) was synthesized as adsorbent to remove cephalexin from water. Attributed to synergistic effect of the electrostatic interaction and coordination interaction between MOF framework and cephalexin, PCN-777 exhibits a high adsorption capacity of 442.48 mg·g-1, which is higher than those of reported adsorbents. The adsorption behavior follows Langmuir model and pseudo-second-order model. Besides, this MOF can be reused via a simple method. Therefore, PCN-777 may have a promising potential application for purification of waste water containing trace antibiotics.

Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
