Abstract: For the adsorption and elution of opium alkaloids the best are ion exchangers of type Katex N if they have a firm structure, do not change in the acid or alkali medium, and are resistant against org. solvents. These Katexes have an active SO₃H group on the ring. The smaller the granulation of Katexes the better the adsorption. The adsorption of alkaloids takes place well in either H or NH₄ cycle, but the NH₄ cycle is preferable because the alkaloids are adsorbed in two phases.
