By: Maggie Tan, LANXESS Pte Ltd The combination of ion exchange resin and iron oxide has various advantages from a mechanical and hydraulic point of view. The plastic matrix of the ion exchange resin gives the material high mechanical stability and allows the specific shaping of the particles. LANXESS has thus succeeded in producing a non-dusting, free-flowing bulk material with a uniform bead size (monodispersity) Although Lewatit FO36 was designed by the Ion Exchange Resins business unit primarily for adsorbing arsenic, it can also be used for adsorbing other trace impurities. LANXESS has thus enhanced its Lewatit range of products with another premium product serving the new market for products to remove trace impurities from drinking water. Health studies show that the arsenic absorbed by the human body through the long-term consumption of contaminated drinking water has the potential to cause cancer or skin problems, even in concentrations of just a few ppb (parts per billion). In line with recommendations made by the WHO, the permitted arsenic content in potable water supplies has therefore been fixed in many countries at less than 10 ppb, which is equivalent to 10 mg per liter. Because this regulation only came into force quite recently in many countries – in the United States, for example, in 2006 – many water suppliers around the world urgently need to take action. # # # LANXESS is a leader in specialty chemicals with presence in 21 countries and is represented at 44 production sites worldwide. The core business of LANXESS is the development, manufacture and sale of plastics, rubber, intermediates and specialty chemicals. End
