D201 is a highly efficient and durable, strong base, Type I macroporous anion exchange resin with quaternary ammonium as the functional group. Its macroporous structure provides high operating capacity and excellent regeneration efficiency and allows complete removal of all anions, including weakly dissociated ions such as silica. This structure with strong basicity also permits the removal of large size soluble organic molecules and imparts superior resistance to mechanical and osmotic shock. The resin is available in both Cl- and OH- form.
D201 is also available with varied particle size to match specific requirement, under different grades, the details are available with our technical service department.

APPLICATIONS: D201 could be applied as simply called macroporous version 201x4, offers greater resistance to oxic-settling-anaerobic process. Mainly used in condensate polishing or make-up mixed beds, where its polymer structure helps in resisting organic fouling. Used in the deionization or demineralization of water, D201 is capable of reducing both strong acid and weak acid concentrations to very low levels. As adsorption application, it also could be used to adsorb gold from the cyanide ore pulp.
CAUTION: Strong oxidizing agents like nitric acid can cause explosive type reaction, when mixed with Ion Exchange resins. Knowledgeable sources should be consulted in the handling of this material.
NOTE: Ion Exchange Resins are sold on a volume basis, but are packed and shipped by weight. The shipping weight for each resin is fixed & does not take into consideration the variations in density and moisture content allowed within the product specifications. Therefore although the weight of the material is constant, there may be slight variations in volume, reflecting batch to batch variation of density and moisture content.
STORAGE CONDITIONS: The resin supplied in drums or bags should be stored in cool shed (warehouse) away from direct sunlight & should be periodically damped down with clean water.
