Biological Activity

[Description]:

Ethylhexadecyldimethylammonium (EHDA) bromide, a surfactant, has been used in a number of adsorptive separational methods, such as the removal of nickel, zinc and chromium ions. Ethylhexadecyldimethylammonium (EHDA) bromide also can be used to prepare dye of staining intracellular ions[1][2].
