Separation of Cadmium Using a new Adsorbent of Modified Chitosan with Pyridine Dicarboxyamide derivative and application in different samples

“…Even though the Cd 2+ ion is a d 10 ion, disturbed coordination geometries are often seen. Generally, the stability of complexes increases with the number of coordination groups contributed by the ligand; consequently, complexes of Cd 2+ with polydentate ligands containing SH groups are very stable [63] …”

Synthesis, antimicrobial activity, urease inhibition and molecular docking studies of new proline linked thiourea derivatives

“…12 Metal complexes of these thiourea derivatives are utilized in supramolecular chemistry, homogenous catalysis, magnetic materials and chemical vapor deposition. 11,13 Keeping in view the above aspects and in the continuation of our previous research work, [14][15] we report herein the synthesis, structural characterization and biological activities of some substituted thiourea derivatives (I a-I e ).…”

“…10 Thiourea derivatives act as selective analytical reagents particularly for the determination of a specific metal in the presence of many other metal ions. [11][12] Thiourea derivatives serve as corrosion inhibitors, and with conjugated sulfur, oxygen or nitrogen donor sites, thiourea derivatives function as good chelating ligands. 12 Metal complexes of these thiourea derivatives are utilized in supramolecular chemistry, homogenous catalysis, magnetic materials and chemical vapor deposition.…”

Synergy Effects in Heavy Metal Ion Chelation with Aryl- and Aroyl-Substituted Thiourea Derivatives

“…Among the most toxic environmental pollutants are heavy metals. − In addition to their toxicity, their persistence in the environment, since they are non-biodegradable; their tendency to biomagnificate; and their bioaccumulative nature make them contaminants whose detection and removal are essential. − Several kinds of heavy metal-detection sensors have been developed, such as biosensors, − electrochemical sensors, − nanomaterial-based sensors, − and optical sensors. − Today, intense research activity is focused on increasing both the sensitivity and selectivity in detection by these devices. − In this way, thiourea derivatives have been developed as a new type of organic ionophores for heavy metal ion selective electrodes. , One of the processes to eradicate such pollutants is chemical remediation, which consists of the complexation of the ions using chelating ligands. − Thiourea derivatives are promising chelating agents of metal cations that have also been proposed for heavy metal ion removal. − Both for sensing and for removal reasons, understanding heavy metal–ionophore activity by organic compounds is thus of high relevance. − In this context, several studies have focused on metal complexes with thiourea derivatives. Coordination chemistry of alkyl and acyl­(aroyl) thioureas of Pt­(II), Pd­(II), and Rh­(III) was reviewed by Koch; the chemistry and metal complexes of acyl-thiourea compounds were recently reviewed in ref ; and uranyl complexes have also been reported with thiourea derivatives …”
