摘要: Abstract The dehydration of CoNaX zeolite single crystals has been observed “in-situ” by UV/VIS microcomputer controlled microscope- spectrophotometry (MMSP) depending upon the temperature in successive limited steps from room up to 350°C. In addition MMSP-method used observe in-situ formation Co 2+ -complexes with dimethylglyoxime (dmgH 2 ) within cavities, dmgH entering gas phase at a given temperature. structural changes undergo during and adsorption are discussed validity method is demonstrated.
