AI Article Synopsis
- Lignin was extracted from sugar beet pulp in Morocco and characterized using FTIR and TG/DTA analysis.
- The lignin was utilized to improve the detection of lead (II) ions through a carbon paste electrode (CPE) using techniques like cyclic and square-wave voltammetry.
- The developed sensor achieved a minimum detection limit of 2.252 x 10^-6 M for lead (II) and effectively analyzed tap water samples for this heavy metal.
Article Abstract
During the present study, biopolymer lignin was extracted, in particular, from sugar beet pulp (molasses) from the Tadla region (224 km from Marrakech, Morocco). The lignin was characterized by infrared spectroscopy (FTIR) and thermogravimetric TG/DTA analysis and then used as a modifier to enhance the electroanalytical detection of heavy metal ion traces. The performance of the lignin/CPE sensor to detect lead (II) was studied by cyclic voltammetry (CV) and square-wave voltammetry in 0.3 mol L NaCl. With optimized experimental parameters, the lignin/CPE sensor developed has a minimum detection limit of 2.252.10 M for Pb (II). The proposed working electrode has been successfully applied for the coanalysis of Pb (II) in tap water with good results.
