| Abstract: | The post-chemiluminescence(PCL) reaction of unsymmetrical dimethyl hydrazine(UDMH) in potassium bromate-luminol system was found.A possible reaction mechanism was proposed based on the studies of the kinetic characteristic of the CL reaction and the reaction conditions including the concentration of potassium bromate and luminol,the length of tube,the velocity of solution flow,the acidity(H2 SO4) of the potassium bromate solution,the alkalinity(NaOH) of the luminol solution.Using the PCL reaction,a new meth... |
