| Abstract: | The method,determination of volatile phenol by waters Sep-Park-C 18 Solid-Phase extraction column,is studied in this paper,The first step is to separate volatile phenol by water vapor still and then develope by waters Sep-Park-C 18 Solid-Phase extraction column.The products of color reaction,eluted by alcohol,can be determined by spectrophotometry.The advantages of this method are light pollution,simple in operation and easy to dispose samples in batches.It can be applied to determination of volatile phenol in food samples with satisfactory results. |
