| Abstract: | Objective To establish an analytical method of determination of Sodium dodecylsulfate in foods by spectrophotometry.Methods Based on the fact that Sodium dodecylsulfate can be determinated when the sample is dipped and extracted by 50% alcohol in the condition of PH8~9 and tempreture 50℃.Results The linear range of the calibration curve was 0~200mg/kg and the limit of detection was 10mg/kg.The rates of recoveries were 96.2%~103.7%.Conclusion This mothod is found to be sensitive,fast and accurate.Therefore,it can be successfully used for determination of Sodium dodecylsulfate in foods. |
| Keywords: | Metlylene blue Spectrophotometry Food Sodium dodecylsulfate |
