稻草亚铵制浆废液氧化铵解改性产物的红外分析

FTIR analysis of ammonia sulfite pulping waste liquor treated with oxide-ammonium

利用红外光谱法定性分析了经过离子交换法萃取分离后的稻草亚铵制浆废液氧化铵解改性产物的有机组分和无机组分,同时将反应原液固形物和改性产物固形物的结构谱图进行了对比,从而推测出稻草亚铵制浆废液氧化铵解反应的历程.

The organic and inorganic components of the ammonia sulfite pulping waste liquor treated with oxide-ammonium were qualitatively examined by FTIR method.The decomposed mechanism of ammonia sulfite pulping waste liquor by oxide-ammonium was analyzed by the comparison of the FTIR chromatogram between the solid components in the black liquor treated and that untreated.
