摘　　要：利用造纸废水中工业木质素的迟效性将其制成长效缓释氮肥是目前造纸工业废水处理的一个较为新兴的研究领域，本文以造纸废水中木质素为原料利用氧化氨解法合成了含氮量较高的木素质肥料，并分析了反应前后产物的结构变化。结果表明，产物含氮量明显上升，分子量降低，芳香结构发生了一定程度的破坏，是一种潜在的有机复合肥料。The synthesis of slow-releasing nitrogen fertilizer by slow-degradability of technical lignin is a new area in the treatment of papermaking waste water. In this study, the lignin fertilizer with high content nitrogen was synthesized from the technical lignin by ammoxidation and its structure was analyzed with FTIR and UV, and its molecular weight was determined. The result indicate that the nitrogen content obviously increased, molecular weight decreased and aromatic struchure was destroyed in some degree. It is a potential organic fertilizer.
