| Octakis(methylthio)porphyrazine have large ring structure and the n electron conjugated system domain.Its symmetry,thermal stability and the semiconductor are very outstanding,and it has catalytic activity and oxygen carrier and other special properties.In this paper,we using Na2(mnt)as the precursor by template synthesis of octakis(methylthio)porphyrazine and its complexes with transition metal(Fe,Co)and characterized.Using DMF as solvent,sodium nitrate as the supporting electrolyte,the octakis(methylthio)porphyrazine and its complexes as cyclic voltammetry using CHi660E.We found that octakis(methylthio)porphyrazine iron complexes have two pairs of redox peaks,and for the continuous electron reversible reaction process;Degradation sodium sulfite solution in DMF,toluene and methanol water(methanol:water=1:1)take advantage of iron complexes.determined the efficiency of octakis(methylthio)porphyrazine iron complexes degradation sodium sulfite in different light conditions,the aerobic/anaerobic conditions.We found that sodium sulfite degradation efficiency is highest in methanol water(methanol:water=1:1)with light and oxygen.Sulfur dioxide and sulphites have been widely used in food processing,because of it have special properties of antioxidant properties,anti-corrosion,preservation,but excessive intake of sulfur dioxide will cause harm to the body.In this paper,the determination of sulfite about plum,wolfberry and jujube.Study on degradation of sulfite on it using octakis(methylthio)porphyrazine iron complexes and this is zhe first.Found the best degradation effect of fruit and vegetable.The burning of fossil fuels and industrial waste gas causes the sulfur dioxide content is higher,so the plant in the near factory contains sulfur dioxide.In this paper,the determination of sulfur dioxide residue in leaves after treatment with octakis(methylthio)porphyrazine on it.Found that the degradation efficiency is 80%indoor and 70%outdoor. |
