Spectroquant® Lead Photometric Test 0.010 – 5.00 mg/l Pb

This Spectroquant^® Lead Reagent Test allows the accurate quantification of the lead(II) ions concentration in aqueous samples. To analyze undissolved or complex-bound lead the sample needs to be decomposed by digestion. Method applied: In alkaline solution lead(II) ions react with 4-(2’-pyridylazo)resorcinol (PAR) to form a red complex which is determined photometrically. The Spectroquant^®Reagent Test Kits contain highly stable, ready-to-use reagent mixtures to perform the analysis according to the procedure described in the accompanying instruction leaflet. All our Cell and Reagent Test Kits are equipped with the unique Live ID (2D barcode) which allows seamless method recognition and contains essential information such as lot number, expiry date, and automatic calibration updates.

• • Simultaneous enrichment and speciation of lead and mercury by magnetic solid-phase extraction coupled to HPLC-ICP-MS: This study introduces a method using magnetic hydrazine-linked covalent organic frameworks for the detection and analysis of lead in various samples, highlighting its applications in environmental monitoring and material science research, essential for assessing heavy metal contamination (Zhang X et al., 2024).
