Two stable cadmium(II) coordination polymers for fluorimetric detection of tetracycline and Fe3+ ions

Preparation of Heavy Metal Trapping Flocculant Polyacrylamide–Glutathione and Its Application for Cadmium Removal from Water

“…When the initial pH of a solution was less than 5, the amino group (-NH 2 ) in polyacrylamide–glutathione acquires hydrogen ions, which protonate -NH 2 to form -NH 3 + . The resulting electrostatic repulsion with positively charged cadmium ions is unfavorable for the coordination of the amino group with cadmium ions [ 46 ]. whereas the carboxyl group -COO-, which can form coordination bonds with cadmium, is hydrolyzed to -COO- in a highly acidic environment, inhibiting the removal of cadmium.…”

Luminescent porous metal–organic gels for efficient adsorption and sensitive detection of chlortetracycline hydrochloride assisted by smartphones and a test paper-based analytical device

“…63 Thereafter, the detection limit of JLUE-MOG-9 for CTC was determined as 0.079 μM, demonstrating JLUE-MOG-9 had high sensitivity to CTC, which was at the same level as in the previous reported literature (Table S10 †). 33,[64][65][66][67][68][69][70] Nevertheless, the potential inferred substances in actual operational environments may have impacts on the fluorescence of JLUE-MOG-9. Satisfactorily, when various inorganic ions were added into the CTC solution, the changes of I 0 /I were acceptable (Fig.…”

A new two-dimensional cadmium(II) coordination polymer based on Cd6(CHADC)6 clusters (H2CHADC is cyclohexane-1,2-dicarboxylic acid): synthesis, structure and properties

“…(CHADC)(H 2 O)] n , (II) [L is 1,6-bis(benzimidazol-1-yl)hexane; Cao et al, 2022]. In (II), the two CHADC 2À ligands display a ( 1 -1 )-( 1 -1 )-2 coordinating mode to connect two Cd II centres to generate a [Cd 2 (CHADC) 2 ] cluster.…”
