| Abstract: | The paper introduced the waste paper deinked pulp was bleached with thiourea dioxide liquor,The effect of thiourea dioxide liquor charge,the ratio of thiourea dioxide fluid,pulp consistaency, temperature and time for thiourea dioxide liquor treatment on the brightness,color reduction were studied. The bleaching effects of thiourea dioxide,H2O2 and Na2S2O4 single stage bleaching were compared. The experimental results indicate that thiourea dioxide liquor is an effective bleaching and decoloring agent for deinked pulp. |
