Kinetics of Decomposition of Cobalt Coordination Complexes on Montmorillonite Surfaces
Institut Agronomique, Universit6 de Louvain, H~verl6-Louvain (Belgium) ABSTRACT MO~TTMOm~LLONrrE may adsorb cobalt(III)hexammine and cobalt(III)chloropentammine cations, and the C.E.C. determined for these complex cations is of the order of magnitude of that obtained with ammonium. The infrared spectra of these coordination complexes adsorbed by the clay are similar to those observed for the co...
متن کاملActivity of Laccase Immobilized on TiO2-Montmorillonite Complexes
The TiO2-montmorillonite (TiO2-MMT) complex was prepared by blending TiO2 sol and MMT with certain ratio, and its properties as an enzyme immobilization support were investigated. The pristine MMT and TiO2-MMT calcined at 800 °C (TiO2-MMT800) were used for comparison to better understand the immobilization mechanism. The structures of the pristine MMT, TiO2-MMT, and TiO2-MMT800 were examined by...
متن کاملSpin-birefringence in molecular currents: Tellurium and gold complexes
We simulate the spin-flip current and transmission function through rings containing elements with a spin–orbit interaction. In a previous study (J. Chem. Phys. 123 (2005) 204714) we predicted that such a system can show spin-birefringence, i.e., a spin current polarized parallel to the molecular axis can flip its direction due to a phase lag due to the spin–orbit interaction. Here we demonstra...
متن کاملsynthesis of binuclear platinum complexes containing biphosphine ligand
هدف از این مطالعه طراحی یک روش کلی برای سنتز یک سری از کمپلکس های دو هسته ای متقارن سیکلومتاله شده پلاتین (ii) بوده که دارای یک لیگاند پل زن(1,2-bis[bis(pentafluoro-phenyl)phosphino]ethane),dfppe, است. از واکنش cis-[pt(r)2(sme2)2]، که در آنr= para-tolyl ، با یک اکی والان از لیگاند benzo[h]quinoline,bhq، در استون محصول [pt(r)(bhq)(sme2)] که در آن r= para-tolyl بدست می آید. همچنین از واکنش 5/0 اک...
Comparison of Adsorption of Phosphate, Tartrate, and Oxalate on Hydroxy Aluminum Montmorillonite Complexes
-Competitive adsorption between phosphate, tartrate and oxalate was studied on two hydroxy aluminum montmorillonite complexes (A1Mtl.6 and AIMt6), which were prepared by adding a base to pH 5.5 to samples containing 1.6 and 6.0 mol AI per kg clay. The quantities of phosphate, tartrate and oxalate adsorbed were more closely related to the amount of OH-AI species coatings on the montmorillonite t...
