Abstract
In this work, ultrasound-assisted dispersive micro-solid phase extraction (USA-D-µSPE) technique using graphitized carbon nitride (g-C3N4) is proposed for the preconcentration of low level of lead in aqueous samples. In this method, microparticles of graphitized carbon nitride sorbent were dispersed in the samples using ultrasonic bath and Pb(II) ions were directly adsorbed on the surface of g-C3N4 particles. After adsorption and desorption of lead ions from g-C3N4 particles, the Pb concentration was determined by the inductively coupled plasma- optical emission spectroscopy (ICP-OES). The main advantages of this method are high speed, simplicity and cheapness. The effects of pH, sorbent amount, eluent type and time on the recovery of the analyte were investigated. Under the optimized conditions and preconcentration of 10 mL of sample, the detection limit of 1.24 μg L-1 was obtained. The results were validated by standard reference materials (NIST, SRM) and spiking of real samples by USA-D-µSPE procedure.
