The adsorption of 2-phenylphenol, which is an antifungal agent, onto organically modified clay from aqueous sucrose solution was investigated. 2-Phenylphenol was effectively adsorbed on neostigmine-modified smectites and octadecyltrimethylammonium modified smectites even in the presence of sucrose in the starting aqueous solution. Two smectites (a natural montmorillonite, Kunipia F, and a synthetic saponite, Sumecton SA) were used to find clay minerals with lower layer charge density gave larger adsorption capacity for 2-phenylphenol. The result showed the potential application of the organically modified clays to remove 2-phenylphenol from orange extracts.Graphic abstract.
