摘　　要：CdO(cadmium oxide)nanoparticles show a strong peak of Plasmon absorption in ultraviolet-visible zone.A strong interaction exists between the surface of CdO nanoparticles and aryl mercaptan compounds.Aryl mercaptan compounds cause aggregation of CdO nanoparticles linked to DNA/RNA(eoxyribonucleic acid/ribonucleic acid)and hence,lead to widening of peak Plasmon of CdO nanoparticles surface at 550 nm and emerge a new peak at higher wavelength.In the current project,this optical characteristic of CdO nanoparticles is used to investigate interaction time between different aryl mercaptanes and CdO nanoparticles.The results showed that aryl mercaptan compounds with shorter chain length interact faster with CdO nanoparticles.Therefore,a simple and fast method for identification of aryl mercaptanes with various chain lengths using red shift in surficial Plasmon absorption is presented.
