How to use the chelating ability of PAA to treat heavy metal ions in industrial wastewater?

April 21, 2025April 21, 2025 admin No Comments

Using polyacrylic acid (PAA) to treat heavy metal ions (e.g., Pb²⁺, Cd²⁺, Cu²⁺, Hg²⁺) in industrial wastewater leverages its carboxylate (–COO⁻) chelation and electrostatic adsorption capabilities. Here’s a step-by-step guide to optimize the process: 1. Mechanism of PAA Chelation Carboxylate Binding: PAA’s –COO⁻ groups form stable complexes with metal ions via bidentate or bridging coordination, especially with transition metals (e.g., Cu²⁺, Ni²⁺) and heavy metals (e.g.,…
