Hydrotalcite (Cat.No:I028979) is a naturally occurring mineral or synthetic compound with a layered structure. It is composed of positively charged layers of metal hydroxides with interlayer anions. Hydrotalcite has excellent adsorption and ion exchange properties, making it useful in applications such as water treatment, catalysis, and as a stabilizer in polymers.
