Abstract:
In this method to amounting of the trace little amount of Pd (II) ions in aqueos Samples bynano graphene with aminopropyltriethoxysilane (APTES) on surfactant coated C18 which in orderto improve the performance of extraction and preconcentration was used. Amounting of theions density in solution was performed by the method of flame atomic absorptionspectrometry. The effective parameters on extraction such as: effect of pH, the amount andeluent solvent, time of extraction and effect of other cation were optimized. Concentratefactor was found 30 and LOD method of limit of detection was found to 0.032µg.L-1. therelative standard deviation is 0.81% (RSD%).
Keywords:
