Nano alumina monohydrate

Nano Alumina Monohydrate (NanoCeram ) Electropositive Filter... 

The filter s active component is a nano alumina monohydrate fiber, only 2 nm in diameter and with an external surface area of 500 m /g. It has been identified as crystalline boehmite (AlOOH) using x-ray diffraction. The isoelectric point of raw fibers is approximately 11.1 (7). Particles with an electronegative charge are attracted and retained by the nano alumina. The nano alumina is bonded by a proprietary process to a microglass fiber that serves as a scaffold in a non-woven media.

The component that contributes to the electropositive character of the filter is a nano alumina monohydrate fiber that is attached to a microglass fiber scaffolding. This smdy has demonstrated that non-fibrous fine and nano size particulate can be attached to the nano alumina by electrostatic forces. Once there they can provide adsorptive capability for chemical toxins that the original media is unable to retain.
