Mixed ligand complexes of palladium(II) and platinum(II) with methionine and 2,4-disubstituted pyrimidines

Adsorption behaviour of cadmium on L-methionine immobilized on controlled pore glass

“…The terminal carboxylic acid and SH-binding site in metallothioneins is more stable than binding by SH groups alone [18]. In the particular case of L-met, the thioether group of the molecule is not the primary binding site in any case, but depending on the number and location of this group, they have some contribution to the binding [19,20]. L-met specifically retained ions such as seleniate [21,22], antimoniate [23], vanadate [24], and aluminium [25].…”

Coordination behavior and biopotency of N and S/O donor ligands with their palladium(II) and platinum(II) complexes

“…Several binary and ternary complexes of Pd(II) and Pt(II) were reported with nucleic acid constituents, amino acids and other nitrogen * Corresponding author. E-mail: kudiwal@datainfosys.net containing ligands [7][8][9]. Metal complexes of semicarbazones and thiosemicarbazones have aroused considerable interest in view of their industrial and biological importance.…”

Study on active coke‐based adsorbents for SO2 removal in flue gas

“…The stronger peak at 3430 cm ‐1 assigned to O–H bonds were observed in the spectra of A–H and A‐H‐8‐7 . The new peaks of A‐H‐8‐7 at 2922 cm ‐1 , 1435 cm ‐1 , 1046 cm ‐1 , 880 cm ‐1 and 532 cm ‐1 were due to the aliphatic carbon–hydrogen bond, C = N and C = C, C = O M = O, M–N and M–O (M means metal) . It showed that metal modification resulted in a large number of unsaturated groups and chelating bonds formed in the active coke, which facilitated chemical adsorption of SO 2 .…”
