There- fore, an effective method was established to determine simultaneously the contents of 22 kinds of phthalate plasticizers in leather products. The proposed method was simple, rapid and sensitive. At the condition of signal/noise (S/N) = 3, the detection limits were 2.00 mg/kg for DIDP and DINP while the detection limits were all less than 0.20 mg/kg for the other twenty kinds of phthalates. The spiked average recoveries changed from 90.80% to 100.49%. The relative stan- dard deviation (RSD) of precision experiments was all less than 7%. The proposed method was applied successfully in the determination of phthalates in commercially available leather products.
