| 摘 要： | 用合成的双倍焦糖色素模拟糖蜜酒精废液中的焦糖色素，研究了硫酸介质中低品位软锰矿氧化降解焦糖色素的脱色动力学，考察了焦糖色素初始浓度、硫酸浓度、软锰矿用量和反应温度对焦糖色素降解脱色速率的影响. 结果表明，焦糖色素的降解脱色速率随焦糖色素初始浓度、硫酸浓度、软锰矿用量和反应温度的增加而增加. 对实验数据进行拟合，得到了焦糖色素降解脱色动力学模型，其脱色过程的表观活化能为24.4 kJ/mol，焦糖色素、硫酸和软锰矿的表观反应级数分别为2.0, 0.58和1.09.

| Abstract: | The caramel in molasses alcohol wastewater was simulated with synthesized diploid caramel, and the decolorizing kinetics of its oxidation degraded by low-grade pyrolusite studied. The effects of reaction temperature, pyrolusite dosage, initial concentration of caramel and sulphuric acid on the decolorizing rate of caramel were investigated. The results showed that the decolorizing rate increased with the increase of reaction temperature, pyrolusite dosage, initial concentration of caramel and sulphuric acid... |
