Successful complexation of the exchanged transition metals by the tetradentate ligand salen was indicated by the typical yellow/brownish colour of the prepared inclusion compounds. X-ray powder diffraction and scanning electron microscopy reveal that the crystallinity of the zeolite host is virtually retained during the modification steps. Furthermore, no crystals of the salen ligand or of metal-salen complexes are visible on the external surface of the zeolite crystallites after careful piuification via soxhlet extraction with acetone. Analysis of the used solvent by UVATS-spectroscopy revealed that only salen but no metal-salen complexes were removed from the zeolite during extraction. This indicates that the complexes are truly entrapped in the intracrystalline voids of the zeolite. It has been demonstrated [7] that the presence of salen and PdSalen in zeolite Y can be probed by IR-spectroscopy in... 

Petrowitz (1986) investigated the release of the active substances of wood preservatives from chemically treated building timbers. He used glass containers with 1.5 1 volume and an air exchange of 4 h at 20 °C. Pine and spruce wood (50 cm ) were treated with 250 ml/m (lindane and endosulfane 1 %, dichlofluanid 0.5 %, PCP 5 % in Shellsol AB). Sampling was also done with activated carbon (4 g) followed by elution with toluene and acetone. Analysis was done by GC-ECD using aldrine as internal standard. 

GC-FID, GC/MS, and HPLC are the suitable instrumental techniques for acetyl acetone analysis.
