摘要：

The degradation behaviour of sodium 1-(2-methylphenylazo)-2-hydroxy-3,6-naphthalenedisulphonate (o-TR) by sodium hypochlorite solution in the presence of ionenes was investigated by means of visible absorption spectrum measurements. The degradation rate of o-TR markedly changed with the ionene concentration. The visible absorption spectra of the aqueous dye solutions in the presence of the ionenes were measured to clarify the situation of o-TR in the ionene solutions. It was found that dye o-TR aggregated in a solution with a certain ionene concentration, this concentration being consistent with the concentration at which the degradation rate became the slowest. It is therefore concluded that the degradation rate of the dye aggregate is significantly slower than that of the dye monomer.
