Separation and preconcentration of copper ion from aqueous solutions by using solid phase extraction with Mebqb as a ligand that immobilized on the naphthalene and graphite Elham Sadeghi Elham@ch iut ac ir 10 Mar 2009 Department of chemistry Isfahan University of technology Isfahan 84156 83111 IranDegree M Sc Language FarsiSupervisor Prof Behzad Rezaei rezaei@cc iut ac irAbstract At this thesis methods for preconcentration and separation of copper ion is presented The methods hasbeen developed for extraction and pre concentration of copper with N N 4 methyl 1 2 phenylene diquinoline 2carboxamide Mebqb as a ligand that immobilized on the naphthalene and graphite copper was eluted from sorbent by suitable elution Flame atomic absorption spectrometry FAAS was usedfor determination of copper ions in eluted solutions The detection limit in two methods was 0 001 g mL 1 A pre concentration factor was 400 for Mebqb naphthalene absorbent and 200 for Mebqb graphiteabsorbent Adsorption capacity were 16 1 mg g copper Mebqb graphite and 2 6 mg g copper Mebqb naphthalene The relative standard deviation Mebqb naphthalene absorbent for five independentdeterminations reached values of 2 0 and 2 3 for copper solutions of 0 1 and 5 0 g mL 1 respectively Therelative standard deviation Mebqb graphite absorbent for three independent determinations reached values of2 4 for copper solutions of 5 0 g mL 1 This procedure has been successfully applied to separate anddetermine the ultra trace levels of copper in the environmental samples free from the interference of somediverse ions Copper has been determined in river tap and waste water samples with recoveries of 92 to105 with Mebqb graphite as absorbent and 98 to 103 with Mebqb naphthalene as absorbent Key WordsCopper Solid phase extraction Water samples preconcentration Mebqb
