Abstract Sodium oleate was adsorbed by phosphogypsum and fly ash as composite adsorbent, and chemical modification was used in the test. Zirco-nium oxychloride was used as modifier. The test proved that modified phosphogypsum/fly ash in 10% zirconium oxychloride solution had the best adsorption effect on sodium oleate, and the adsorption rate reached 86%. Zr modified phosphogypsum/fly ash composite adsorbent were characterized by XRD, IR and SEM, and the effect of pH, temperature, solution concentration, adsorption time on the absorption of sodium olea-te was studied. The results showed that the optimal adsorption pH range was 7—9, the adsorption equilibrium time for 30 min, at 25 ℃ saturated adsorption capacity was 14.376 mg/g. The adsorption isotherm accorded with Langmuir isothermal model, the adsorption kinetics conformed to the quasi second order dymamics model. The adsorption process was exothermic reaction, and the heat of reaction was -15.969 J/g.

Key words： phosphogypsum fly ash adsorbent sodium oleate adsorption kinetics adsorption isotherm
