In this work, the Nanofibers were synthesized using electrospun of polystyrene solution in DMF/ THF solvent. The important parameters such as voltage, the distance between injector and collector, speed injection, the concentration of polystyrene and speed rotation of collectors in electrospun technique were optimized. Results showed that, within certain limits, by increasing the voltage, high Electro distance, low injection rate and high speed of the collector, we will get the Nanofibers with diameters less and regular chain structure. In optimal conditions, the average of polystyrene fibers diameter was 70-102 nm. Polystyrene absorbent modified by dithizone. By selecting the best conditions, the modified polystyrene Nanofibers were produced with an average diameter of 73-126 nm. The synthesized polystyrene Nanofibers were used for preconcentration of Copper in wastewater samples. The effective parameter on extraction such as adsorbent amount, pH, type and volume of eluent solvent and salt amount was evaluated and optimized with “one at the time” method. According to the results, optimum conditions are the solid phase: 0/006 gr, pH = 7, eluent solvent: acetonitrile solution with a volume of 0/7 mL, 1/3 g amount of potassium nitrate salt. This method was applied to real samples and good results were obtained. High enrichment factors and very good detection limit are highlights of this method.
