摘要: ABSTRACT An on-line lead preconcentration and determination system implemented with inductively coupled plasma atomic emission spectrometry (ICP-AES) associated to flow injection (FI) ultrasonic nebulization (USN) was studied. For the retention of lead, 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol (5-Br-PADAP) Amberlite XAD-16 were used, at pH 9.2. The removed from microcolumn in counter nitric acid. A total enhancement factor 150 obtained respect ICP-AES using pneumatic (15.0 for USN 10.0 column). detection limit value 10 mL aqueous solution Pb 0.2 ng mL−1. precision 10 replicate determinations 5 ng mL−1 levels 2.8% relative standard deviation (RSD), calculated peak heights obtained. calibration graph linear a correlation coefficient 0.9997 near limits up least 100 ng mL−1. The...
