摘　　要：采用双甲酮法、过滤法和离心法3种方法进行对比试验,分析比较了各方法的优缺点,并对不同方法所做的浑浊样品、阳性样品检测结果进行了分析,得出了如下结论:采用过滤法对萃取液浑浊的纺织品进行甲醛测试结果准确度高,实验操作简单,检测效率高.过滤法是针对纺织品甲醛检测中萃取液浑浊时可采取的一种快速准确的试验方法.In this paper, three methods,i, e. dimedone method, filtration method and centrifugation method, were used for the test of formaldehyde contained in textiles. The suitability and accuracy of these methods were compared based on the formaldehyde test results of three type of samples, i.e. samples containing formaldehyde and giving turbidextract liquor, samples containing formaldehyde and giving clear extract liquor, and the mixtures of the above two types of samples. It was observed that thefiltration method was the only one that could prevent the interference of turbidity of extract liquor and gave correct results for all the samples. In addition, this method is also accurate and con- venient for operation.
