Abstract

A new and novel poly(vinyl benzyl dithiocarbonate-dimethyl amino ethyl methacrylate) block copolymer (PvbDMA-Xa) as adsorbent was synthesized for the vortex-assisted dispersive solid phase microextraction (VADSPME) of patulin from apple products and dried fruits using Uv-visible spectrophotometer. The characterization of synthesized Pvb-DMA-Xa block copolymer was performed with Fourier Transform Infrared spectroscopy (FTIR-ATR) technique. Analytical characteristics such as pH, sorbent amount, adsorption time, eluent type and its volume, desorption time and adsorption capacity were optimized. Limit of detection (3Sb/m) and limit of quantitation (10Sb/m) were found 0.3 and 1.0 ng mL-1. Linear dynamic range (LDR), relative standard deviation (RSD) and recovery values were found in the range of 1-30 ng mL-1, 2.1-2.7 % and 93.5-97.3 %, respectively. Enhancement factor (EF) was found 193. The accuracy of the method was confirmed with standard addition method and analyzing of samples by reference method.
