| 摘 要： | 在酸性条件下，采用乙酸乙酯萃取、Na2HPO4溶液反萃取分离酱汪、食醋中的山梨酸、苯甲酸，卡尔曼滤波法计算结果，并与比值导数波谱法进行比较。结果表明，卡尔曼滤波法较地数波谱法有较高准确度和精密度，并能监测干扰物质存在与否。用于实际样品分析有更高的可靠性。

| Abstract: | The benzoic acid and sorbic acid were re extracted with Na 2HPO 4 solution from the acetic ether,with which the soy and vinegar were extracted in acid solution.The UV spectrum of the Na 2HPO 4 solution was calculated with kalman filter method.The results of benzoic acid and sorbic acid are better than those obtained by derivative ratio spectrum method.The kalman filter method has a higher reliability and accuracy,and can detect the interference in real samples. |
