Palladium-Activated Carbon Ethylenediamine Complexes

Chemically modified activated carbon with ethylenediamine for

Carbon active chemically bonded ethylenediamine as one sorbents successfully were applied for the enrichment of trace amount of some metal ions. The influences of the variables including pH, amount of solid phase, sample flow rate, type and condition of eluting solution and sample volume on the metal ions recoveries were investigated. The method has high sorption-preconcentration efficiency eve...

Recovery of Palladium from Spent Activated Carbon-Supported Palladium Catalysts

TÜBİTAK Marmara Research Center, Chemistry Institute, 41470 Gebze, Kocaeli, Turkey Email: [email protected] Activated carbon-supported palladium catalysts are liable to progressive deactivation even in the absence of any gaseous contaminants during the oxidation of hydrogen under ambient conditions. The high value of palladium coupled with environmental considerations means that n...

Synthesis and Characterization of Nickel and Zinc Sulfide Ethylenediamine Complexes

In the present work, nickel and zinc sulfides ethylendiamine (N2H4C2H4) complexes were prepared in an autoclave at 180 C for 12 h. Transmission electron microscope (TEM) and X-ray powder diffraction were used to study the morphology of the two samples. The infrared absorption spectra were obtained and discussed in the range (200-4000 cm). New bands appeared at about 238,240 and 297 cm assigned ...

Phospholipid-metal complexes. Interaction of triphosphoinositide- and phosphatidylserine-metal complexes with ethylenediamine, polyaminoacids, and protein.

Preparation of Microwave Absorbing Nickel-based Activated Carbon by Electroless Plating with Palladium-free Activation

Nickel-based activated carbon was prepared from coconut shell activated carbon by electroless plating with palladium-free activation. The materials were characterized by scanning electron microscopy (SEM), X-ray energy dispersion spectroscopy (EDS), vibrating sample magnetometry (VSM), and vector network analyzer, respectively. The results show that the surface of the activated carbon was cover...
