Optimization of Parameters for the Determination of Sulfur Dioxide in Laboratory Based on One-Way Analysis of Variance
Sulfur dioxide is a commonly used exogenous food additive and is often used in the production of rice noodles,bean curd sticks,candied fruits and dried vegetables.From the perspective of improving laboratory testing efficiency,this paper optimized the parameters for laboratory determination of sulfur dioxide by performing one-way analysis of variance on four influencing factors:heating power,hydrochloric acid addition,nitrogen flow rate and reaction time.The results showed that the most suitable experimental conditions were heating power of 100 W,hydrochloric acid addition of 8 mL,nitrogen flow rate of 0.8 L·min-1 and reaction time of 80 min,which improved the testing efficiency of sulfur dioxide.
