U. Hechler et al., COMPARISON OF DIFFERENT EXTRACTION METHODS FOR THE DETERMINATION OF POLYCYCLIC AROMATIC-HYDROCARBONS IN SOIL, Fresenius' journal of analytical chemistry, 351(6), 1995, pp. 591-592
Two different extraction methods for the determination of polycyclic a
romatic hydrocarbons in soil are compared: the extraction in combinati
on with ultrasonic treatment, and the Soxhlet extraction method accord
ing to DIN-draft 38414 Part 21. Different types of real soil were extr
acted and analysed by HPLC with diode-array detector and fluorescence
detection. The results show that the efficiency of the ultrasonic meth
od is comparable to the Soxhlet method.
