摘　　要：目前国内外绝大多数废新闻纸化学脱墨工厂采用碱性脱墨法,但是碱性脱墨剂有许多不可避免的缺点,如废水COD较高,纸浆容易碱性变黑等。本文针对碱性脱墨的缺点,研制出了可在中性条件下脱墨的中性脱墨剂,并对中性脱墨剂的应用条件进行了探讨,与碱性脱墨剂的脱墨效果作了对比。Up to now, deinking of waste newspaper is done predominantly under alkaline conditions. But many shortcoming were existed inthis kind of method. The neutral deinking agent was manufactured and its application was studied in this paper.
