HPLC Analysis of Aliphatic Sulfonate Surfactants using Ion-Pair Detection
(Journal article; Peer reviewed, 2005)A method was developed for the analysis of a number of surfactants which contained no UV-chromophores, using RP-HPLC with Indirect Photometric Detection, IPD. Pyridinium salts such as N-methylpyridinium iodide, ... -
X-ray absorption spectroscopic studies on active metal sites in zeotypes during the selective catalytic reduction of NOx with propene in an oxygen rich atmosphere
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:130, Doctoral thesis, 2005)This thesis is concerned with the synthesis and characterisation of CuAPO-5, CuSAPO-5 and also copper ion-exchanged SAPO-5, SAPO-11 and ZSM-5. The ability of these materials to catalyse the selective reduction of NOx using ... -
Synthesis of Hydroxy Sulfonate Surfactants
(Journal article; Peer reviewed, 2005)The selective synthesis of sulfonate surfactants with side chains containing ether- and hydroxy groups was carried out using cyclic sulfates as epoxide analogues. The main chain was elaborated from 1,2-dodecane sulfate ... -
Immobilization does not influence the enantioselectivity of CAL-B catalyzed kinetic resolution of secondary alcohols
(Journal article; Peer reviewed, 2005)Decreasing enantioselectivity (E-value) by conversion has been observed in transesterification reactions of secondary alcohols catalyzed by a pure protein formulation of lipase B from Candida antarctica (Novozym 525 F). ... -
Investigation of selected natural and anthropogenic radionuclides in reindeer (Rangifer tarandus tarandus) and lynx (Lynx lynx)
(Doktoravhandlinger ved NTNU, 1503-8181; 2005:151, Doctoral thesis, 2005)The present thesis investigates a range of dietary, physiological and environmental factors influencing transfer and long-term behaviour of radionuclides in reindeer and lynx. Feeding experiments were designed to provide ... -
