Study on the Determination of Oils in Marine Sediments by Ultrasonic Extraction Ultraviolet Spectroscopy
Using ultrasonic extraction and centrifugal separation methods instead of manual oscillation extraction and funnel washing separation methods to extract oil from marine sediments,study the optimal experimental conditions,and compare the methods with standard methods.The experimental results show that the ultrasonic extraction method has an overall recovery rate 10 percentage points higher than the manual oscillation method,and the workflow is simple,the operation is convenient and fast,reducing the error of multiple transfers of the extraction solution,and improving the precision and accuracy of the analysis method while improving work efficiency.
