The procedure of MSPD is simple and not time-consuming. C18-bonded silica and anhydrous alumina were, respectively, used as dispersion sorbent and purificant, and dichloromethane as extraction reagent. Under the optimum conditions, seven kinds of herbicides were separated completely within 30min, response was a linear function of concentration over the range 2.5-500μgL−1 with good correlation coefficients (>0.99) and lower detection limits (0.25 and 0.5μgL−1). Intra-day and inter-day precision of the peak areas for seven PUHs were less than 3.7 and 5.3%. The new method was used to detect seven PUHs in four kinds of solid foodstuffs with average recoveries range from 73.1 to 101%.
