چکیده مقاله:
In this method to amounting of the trace little amount of Zn (II) ions in aqueos Samples bysynthesized by chemically converted graphene sheets by C18 (CCG) which in order to improve theperformance of extraction and preconcentration was used. Amounting of the ions density in solutionwas performed by the method of flame atomic absorption spectrometry. The effective parameters onextraction such as: effect of pH, the amount and eluent solvent, time of extraction and effect of othercation were optimized. Concentrate factor was found 40 and LOD method of limit of detection wasfound to 0.032µg.L-1. the relative standard deviation is 0.81% (RSD%).
