大葱清除亚硝酸盐影响因素的研究

Study on the effect of Chinese onion on removing nitrite

对大葱清除亚硝酸盐的影响因素进行了研究。考察了大葱液的性质及其稳定性;测定了大葱液对亚硝酸盐的清除率以及反应时间、pH、大葱液浓度等对清除率的影响。研究表明,大葱液的性质不稳定,并且对亚硝酸盐的清除率受多种因素影响。

The effect of Chinese onion on removing nitrite was studied. The properties and stability of Chinese onion solution were observed. The removal rate of by Chinese onion was determined, and its affecting factors （reaction time, pH, the concentration of Chinese onion solution, etc） were studied. The results showed that the properties of Chinese onion solution were instable,and the removal rate was affected by various factors.
