Abstract

 In this work, polyamidoamine dendrimer G(1. 5) supported on SBA-15 nanoporous is used as a novel sorbent for extraction and determination of Pb ions from environmental water specimens utilizing flame atomic absorption spectrometry. FTIR spectrum and thermal analysis were used to represent the existence of dendrimer groups in the silica framework. The various parameters like pH, concentration of eluent, extraction time, and interfering ions on extraction efficiency were studied. Pb 2+ and Cu 2+ and Cu 2+ ions were completely extracted at pH= 5-8 after stirring for 5 minutes. The minimum quantity of acid for stripping the ions from SBA-G1. 5 was examined and the pre-concentration factor of the technique was 233 for both of ions. Under the optimized conditions, the linearity of the technique was within 10-40 ng mL 2+ were 5. 0 and 1. 2 ng mL − 1 Pb 2+ and 2-20 ng mL − 1 Cu 2+. Detection limits for Pb 2+ and Cu 2+, n=5) were 2. 9 % and 2. 1 %, respectively. There was good consistency between the measured and added amount of Pb-1 and the relative standard deviations (RSD, %, C=15 ng mL-1, n=5) were 2. 9 % and 2. 1 %, respectively. There was good consistency between the measured and added amount of Pb2+ and Cu 2+ in spiked distilled water which indicates good accuracy of methods. The capability of the method in a real sample was tested in various Water samples.
