| 摘 要： | 对乙酰丙酮分光光度法测定4%乙酸（v/v）和3%乙酸（w/v）酸性食品模拟液中游离甲醛的实验条件进行了优化和改进。在优化试验条件下,在0.011～2.2μg/mL范围内呈现良好的线性,线性相关系数均大于0.999,且方法检出限可达0.0084μg/mL。改进后方法可用于检测食品接触材料在酸性食品模拟液中微量游离甲醛含量。

| Abstract: | The experimental condition of determination of trace free formaldehyde in 4% acetic acid（v/v）and 3% acetic acid（w/v） acidic food simulant by spectrophotometry with acetylacetone were optimized and improved.Under the optimized conditions,the absorbance intensity was nicely linear over a range of 0.011～2.2μg/mL,the correlation coefficient was more than 0.999,and that the detection limit was 0.0084μg/mL.The improved method can be applied to determine the trace free formaldehyde which migrated from plastic food contact materials in acidic food stimulant. |
