摘要: Abstract The adsorption behaviour of o-phenylenediamine and its catalytically formed oxidation products such as 2,3,-diaminophenazine higher-molecular-weight compounds on different varieties asbestos is studied by using laser desorption mass spectrometry. results prove that amosite adsorbs the product more easily than do crocidolite anthophyllite, whereas U.I.C.C. chrysotile A does not give rise to detectable adsorption, observed for B only fair. method shows potential investigation surface reactivity pure industrially transformed other fibrous materials.
