Ethylene Absorber KMnO4 Activated Alumina
Chemxin Activated Alumina KA407 is activated alumina containing a minimum of 8 % potassium permanganate, evenly distributed in the pores, which permanently eliminates the con- taminants via an oxidation reaction to inactive solids. It is very good efficiency in Air purification. Because of strong oxidizing property of Potassium Permanganate (KMnO4), it could remove Hydrogen Sulfide(H2S) , chlorine(CL2),formaldehyde(HCHO), nitric oxide (NO) & sulfur dioxide(SO2) from air. Activated balls with potassium permanganate adopts special activated alumina carrier, after a high-temperature solution compression, decompression and other production processes, the adsorption capacity is more twice than the similar product .As the high strength and long usage time,it can be rated as the first-class products in domestic market. With the strong oxidizing property,it can decompose the harmful gas with reductibility in the air in order to clean the air ,and it also has the high efficiency to removal other harmful gases such as the hydrogen sulfide, sulfur dioxide, chlorine, formaldehyde, nitric oxide, etc.

CHEMXIN adsorbents are shipped in air-tight, non returnable drums or bags. See our Standard Offer for Packing, Marking and Expedition for details. In all cases we recommend to warehouse the pallets indoor in order to prevent them from bad weather conditions (rain, sand storm, etc.), direct sun and ground humidity. Outside storage is not recommended, in particular for bags.
The drums can be stored up to 5 years under cover. Bags cannot be stored for more than 2 years, even under cover. For longer storage durations, we recommend to sample and analyse the products, in order to make sure they are still fit for use. These recommendations are general and may slightly differ depending on the product type, packaging, storage location, etc. In any case, ask CHEMXIN to make sure your storage conditions meet our requirements.
