Lewatit® FO 36
Lewatit® FO 36 is a macroporous, monodispersed, weakly basic, polystyrene-based ion exchange resin for the selective adsorption of oxoanions, such as arsenate or arsenite ions. It is doped with a nano-scale film of iron oxide covering the inner surfaces of the pores of the polymer bead. Target oxoanions are bonded by a specific, reversible reaction involving hydroxy-groups on the iron oxide surface.
Lewatit® FO 36 is especially suitable for use in the following applications:
In the purification of potable water arsenic can be removed down to rest concentrations significantly lower than 10 µ g/l which is the maximum contaminant level set in several countries. Lewatit® FO 36 is also capable of adsorbing other species such as HPO 4 2-, HSbO4 2-, SCN- etc.

LANXESS at EverythingAboutWater EXPO 2011, <br>Mumbai, India, January 6 to 8, 2011
Premium products for water treatment
Specialty chemicals group LANXESS will be showcasing itself with premium products for water treatment from its Lewatit range at the EAW (EverythingAboutWater) EXPO 2011 trade fair in Mumbai in India. “As one of the world’s leading trade fairs for drinking water, industrial water and wastewater treatment, the EAW gives us the ideal platform for demonstrating our expertise as a single-source supplier of ion exchange and adsorber resins for this market,“ said Prakash Shanmugam, head of Marketing & Sales for the Indian subcontinent in the Ion Exchange Resins business unit. “It also provides us with an important gateway to the Indian water industry and other correspondingly large Asian markets.” The focus of LANXESS’ exhibition will be not only on Lewatit adsorbers and functional polymers but also on the gel-type cation exchange resins Lewatit MonoPlus S 108 and Lewatit MonoPlus S 108 H. These are used primarily in industrial water treatment, for example to demineralize water for the industrial steam generation.
At the congress taking place in parallel to the EAW fair, Kedar Oke, Senior Manager Technical Marketing in the Ion Exchange Resins business unit, and his colleague Dr. Mandar Maduskar will give two presentations on applications of ion exchange and adsorber resins in potable water and wastewater treatment. “Alongside industrial water treatment for the semiconductor and pharmaceutical industries and for the food and energy sectors, this is another attractive field for our products,” remarked Oke.
Demand for clean water worldwide will increase by around a third by 2030. This growth in the water requirement will be particularly pronounced in Asia, especially India, because of the spiraling population and universal urbanization. LANXESS therefore sees Asia as one of the most important growth markets for products for water treatment and has built one of Asia’s most state-of-the-art ion exchange production facilities in India. The recently inaugurated plant in the Jhagadia Chemical Park in the Indian state of Gujarat has an annual capacity of 35,000 metric tons.
LANXESS is a leading specialty chemicals company with sales of EUR 5.06 billion in 2009 and currently around 14,500 employees in 23 countries. The company is represented at 42 production sites worldwide. The core business of LANXESS is the development, manufacturing and marketing of plastics, rubber, intermediates and specialty chemicals.
