中文摘要: 以沙棘果为原料，采用溶剂提取法制取沙棘果提取物，研究添加量、反应温度、反应时间和反应pH值对沙棘果提取物降解亚硝酸盐效果的影响，优化了沙棘果提取物降解亚硝酸盐的反应条件。结果表明：影响沙棘果提取物亚硝酸盐降解率的主要因素是反应pH值，其次是反应温度和添加量，反应温度和pH值之间的交互作用对亚硝酸盐降解率影响显著。在提取物添加量6 mL，反应温度50 ℃，反应时间20 min，pH 2 的反应条件下，沙棘果提取物亚硝酸盐降解率达到96.10%。
Abstract:Sea buckthorn fruit was used as raw material，and its extract was obtained by the method of solvent extraction. The effects of additive amount，reaction temperature，reaction time and pH value of the extract on nitrite degradation were investigated. The reaction conditions of sea buckthorn fruit extracts on nitrite degradation were optimized. The results showed that the main influencing factor on nitrite degradation was pH value，followed by reaction temperature and additive amount. In addition，the interaction between reaction temperature and pH value had a significant effect on nitrite degradation rate. When the additive amount was 6 mL，the reaction temperature was 50 ℃，the reaction time was 20 min，pH value was 2，the degradation rate of nitrite by sea buckthorn fruit extracts was up to 96.10%.
