“…Our group previously reported the use of coordination polymers for environmental remediation [13,[36][37][38][39]. This work also reports the efficiency of the Zn (II) CP in the adsorption of 2,4,6trichlorophenol (TCP) (Figure 1) solution which is a representative organic compounds found in industrial effluents, especially pulp and paper industries.…”

“…] n was a square-based pyramid (they did not consider the bond O2�M 2+ to be effective), subsequent works consider the existence of the bond O2� M 2+ and present the copper 8 and zinc 41,43 compounds as a distorted octahedron, similar to the cobalt 9 In the polymeric structures of BioMOFs (Figure 3), the glutamate moiety acts as a multidentate ligand by carboxyl groups and an amino group. This characteristic allows glutamate to coordinate to different metal centers and to act as a bridge in the construction of parallel chains that are grouped in a complex three-dimensional array.…”

“…34 These complexes are difficult to crystallize, making it difficult to resolve their structures. MOFs (BioMOFs or MBioFs) and metal complexes containing glutamic acid have several applications, such as adsorbents, 8,20 catalysts, 21,23,31 and antimicrobial agents. 34,35 The purpose of this work is to present an experimental activity in inorganic chemistry at the undergraduate level that involves transition metals from d 5 to d 10 systems combined with glutamic acid to obtain BioMOFs and metal complexes.…”

Reactions between metal carbonates from d 5 to d 10 systems and glutamic acid are used to obtain molecular metal complexes and metal−organic frameworks (MOFs). When the ligand is an amino acid, these MOFs belong to the BioMOF class (metal− organic frameworks for biological and medical applications). The metal carbonates of the d 5 , d 6 , and d 8 systems produce molecular complexes with general formulas [M(GluH) 2 (H 2 O) 2 ], whereas those of the d 7 , d 9 , and d 10 systems produce compounds of the type [M(Glu)(H 2 O)• H 2 O] n . Through these syntheses one can explore, among others, concepts largely related to coordination chemistry such as crystal field splitting, weak and strong fields, the chelate effect, coordination number, metal−ligand stability series, Jahn−Teller distortion, acidity and basicity concepts, and crystal structure. In addition, these experiments also provide an opportunity to discuss interaction stability between metal ions with carbonate and hydroxide anions expressed by physical−chemical parameters such as absolute hardness and natural indices for chemical softness, as well as by the respective Pourbaix diagrams.

“…Furthermore, the adsorption of ciprofloxacin tailed a pseudo-second-order kinetics, suggesting the existence of physical sorption. Consequently, the outcomes recommended the usage of MOF [Cu(Glu) 2 (H 2 O)]•H 2 O by way of an adsorbent for ciprofloxacin elimination from the wastewater [53].…”

In recent years, the pharmaceutical field has significantly achieved magnificent progress owing to the necessities of human health and life; however, it also led to drastic environmental issues. The existence of pharmaceuticals in water bodies, which could cause adverse effects on human beings and environment, rose up distress worldwide. The pharmaceutical components found in water bodies have mainly two origins: manufacturing procedures in pharmaceutical industry and common usage of pharmaceutics. The essence of pharmaceutical wastewater (PWW) is intricate, including large amount of organic matter, high salt, microbial toxicity, and non-biodegradable. In sight of water scarcity means, it is essential to figure out and expand techniques for pharmaceutics derived wastewater in water management. Nevertheless, numerous treatment methods have been established to serve pharmaceutical wastewater including biological treatments, membrane technologies, hybrid technologies, advanced oxidation processes, absorption methods, etc. Recently, metal organic frameworks (MOFs), metallic ions clusters linked with organic bridging linkers, have been utilized in number of uses such as storage, separation, sensing, catalysis, adsorption, and many others. The viability of MOFs toward wastewater treatment (WWT) for various pollutants is fundamentally because of the extreme porosity, discrete pore structure, and superficial modification. This chapter highlights the origin and treatment of pharmaceutical wastewaters via the utilization of MOFs and their hybrid systems. A brief perception of the future work in the field has also been discussed.
