Adsorption and possible luminescence detection of nonylphenol by Eu3+-smectites
4-Nonylphenol was effectively adsorbed on Eu3+-smectites, which were prepared by cation exchange reactions of a natural montmorillonite and a synthetic saponite with Eu3+ chloride, from aqueous solutions. The appearance of luminescence bands of Eu3+ by the excitation of the adsorbed 4-nonylphenol was also observed.
