D860 (Na form) resin is a premium grade, macroporous weak acid cation exchange resin with amino phosphonyl functional groups. It is designed to chelate/remove many heavy metal cations, especially for heavy metals in mining and petroleum refinery drainage and waste water.
It has excellent adsorbing capability. D860 (Na form) resin has even particle size and good mechanical strength. High concentrations of sulfates and chlorides or the presence of chelating or complexing agents can alter this sequence and will affect the operating capacity.
D860 has very strong selectivity to earth metals, such as calcium (Ca++) and magnesium (Mg++), over alkali metals such as sodium (Na+) and potassium (K+). This makes it especially useful in brine softening applications for the chlor-alkali industry.
