| 摘 要： | 本文采用人工老化和自然老化对混合办公废纸脱墨浆H2O2（P）和H2O2－Na2S2O4(PY)漂白返黄进行了研究，PY漂白浆的抗返黄的能力比P漂浆好，且Na2S2O4用量为1．5％时返黄最轻。

| Abstract: | The yellowing of deinked pulps from mixed office wastepaper(MOW) bleached with H 2O 2(P) and H 2O 2_Na 2S 2O 4(PY) respectively is studied with natural aging and oven aging in this paper.The brightnees stability of deinked pulps bleached by PY is higher than that of pulps bleached by P.The yellowing of deinked pulps bleached with 1.5% Na 2S 2O 4 (based on oven dry pulp) is the least in all PY bleached pulps. |

| Keywords: | yellowing deinked pulp sodium dithionite hydrogen peroxide |
