Magnesium aluminum hydrotalcite
Download：
Magnesium aluminum hydrotalcite is a layered double hydroxide (LDH), and its chemical formula is generally represented as: [Mg₁₋ₓAlₓ(OH)₂]·(Aⁿ⁻)ₓ/ₙ·mH₂O. Its structure consists of a positively charged magnesium aluminum hydroxide layer and an exchangeable anion layer, giving it excellent adsorption, neutralization and stability properties.
Introduction
