Toxicity and speciation of phthalocyanine dyes and the synthesis of new tetradentate phosphorus macrocyclic ligands.

摘要

Understanding of how textile effluent is decomposed by ozone is important for environmental applications of ozone decontamination. In the following dissertation, the toxicity of Drimarene K-2B and X-3G along with tetra-sulfo-tetra-sodium salt of copper(II) phthalocyanine dyes has been determined with the use of Lemna Minor (duckweed). The textile effluent of phthalocyanine dyes and their decomposition products, from the reaction with ozone, have been examined by electrospray mass spectrometry (ESMS). The use of ESMS leads to important information connecting the toxicity of the dye solution to solution composition before and after color abatement.; The syntheses of the new chelating compounds [29]aneP4, [34] 4, and [44]ane4 have been carried out. These polyphosphorus macrocyclic ligands were studied by 31P NMR and electrospray mass spectrometry along with DCI mass spectrometry. The synthetic pathway of the new compounds includes the formation of phosphonium salts of the macrocyclic compounds. The phosphonium salts are then hydrolyzed to form phosphine oxides, which are then reduced to form the free phosphine target compounds.; The above mentioned ligands are studied utilizing a transition metal ion probe, AgBF4. The silver(I) complexes formed by these ligands were characterized by 31P NMR, 19F NMR, and electrospray mass spectrometry.
