| Abstract: | The waste paper deinked pulp was bleached with formamaidine sulphinic acid(FAS) or hydrogen peroxide and FAS The effects of FAS charge,ratio of NaOH to FAS,pulp consistency,temperature and time for FAS treatment on the brightness gain,color reduction and pulp strength were studied The results of H 2O 2 FAS and FAS H 2O 2 two stage bleaching were compared The experimental results indicate that FAS is an effective bleaching and decolorizing agent for deinked pulp |
| Keywords: | deinked pulp formamidine sulphinic acid (FAS) hydrogen peroxide bleaching |
