The reaction kinetics of acrolein oxidation over various oxidic catalysts have been investigated. The phases were employed as both pure single phases and mixtures of the single phases. It could be shown that copper molybdate in combination with the active phase (Mo-V-Oxide) improves the selectivity of acrylic acid formation. Simultaneously to the c...
The reaction rate and the ethylene/ethane product ratio in CO hydrogenation increase when cobalt wire, used as a catalyst for the reaction, is reduced to lower extents. The kinetic results obtained with the poorly reduced wire correlate well with temperature-programmed surface reaction (TPSR) and H-2 chemisorption results, and are interpreted to be...

Some triazines and metabolites have been analyzed in water and soil samples, at the 0.1 and 10 ppb level, respectively, by CGC-MS and CGC-MS-MS using an ion trap detector (ITD), The sample preparation consisted of SPE on LiChrolut EN cartridges for water samples, and of ultrasonic treatment followed by SPE for soil samples. Recoveries were in the o...
The momentary used procedures for removing volatile mercury from offgasses are shifting the offgas-problem to a special waste problem, in other words they cannot guarantee a selective removal. The aim of this investigation was the development of stable carriers for selected sorption of mercury-loaded offgasses. The specific ability of mercury formi...

New chelating ion-exchange resins chemically derived from chitosan, a biopolymer which is easily gained from shrimp shells, have been prepared and studied in the absorption of heavy metal ions. In order to study structure-property relationships, in the first stage of this study complexes of glucosamine derivates as model substances have been synthe...
