Hydrotalcite possesses a layered, sheet-like structure with positively charged metal hydroxide layers and exchangeable anions located in the interlayer space. This structure contributes to its unique properties.The anionic exchange capacity of hydrotalcite allows it to exchange and store various anions in its interlayer region. This property is valuable in applications where selective adsorption or ion exchange is required.
Feature：
Hydrotalcite has the chemical formula Mg₆Al₂(OH)₁₆CO₃ · 4H₂O, indicating its composition of magnesium (Mg), aluminum (Al), hydroxide (OH), carbonate (CO₃), and water (H₂O). The combination of these elements forms a layered structure.
Adhibition：
Hydrotalcite is used in medicine as an antacid to neutralize excess stomach acid. Its ability to interact with and neutralize acidic substances makes it effective in treating conditions related to gastric acidity.Wastewater Treatment: Hydrotalcite's anionic exchange capacity is employed as an adsorbent for certain anions in wastewater treatment processes. It can selectively capture and remove undesirable ions from aqueous solutions.
