| Abstract: | In contrast with ground state oxygen,singlet oxygen has a higher chemical reactivity due to its unpaired electrons.In this paper,the properties,generation and application of singlet oxygen were introduced briefly,especially,some study and attempt utilized singlet oxy-gen for pulp bleaching in recent years were Introduced in detail.Those studies indicated that singlet oxygen has stronger degradability oflignin than ground state oxygen,and singlet oxygen has a good bleaching selectivity.In particularly,bleaching with singlet oxygen preparedby photo catalyzing consumes little chemicals and it is environmentally friendly.So,it is necessary to study this subject deeply and it willhave promising practical application future. |
| Keywords: | singlet oxygen pulp bleaching photocatalysis |
