A new, sensitive, and reliable flow injection methodology was investigated for the determination of lead ion (II) in vegetables’ samples using a laboratory-prepared reagent 2-[(6-methoxy-2-benzothiazoly)azo]-4-methoxy phenol (6-MBTAMP). Infrared spectroscopy, UV-visible spectrophotometry, Energy dispersive Xray spectroscopy (EDX), Elemental Analysis (CHN), nuclear magnetic resonance spectroscopy ¹HNMR, and <SUP>13</SUP>CNMR techniques were used to characterize the reagent and lead (II) complex. The method is based on lead ion (II) reacting with the reagent (6-MBTAMP) in a neutral solution to produce a green-red complex with a maximum absorbance at 670 ㎚. The optimum conditions, such as flow rate, lead ion (II) volume, reagent volume, medium pH, reagent concentration, and reaction coil length were thoroughly examined. The limits of detection (LOD) and quantification (LOQ) were determined to be 0.621 ㎎·L<SUP>−1</SUP> and 2.069 ㎎·L<SUP>−1</SUP>, respectively, while Sandell"s sensitivity was determined to be 0.345 ㎍·㎝<SUP>−2</SUP>.
