A new diffusive gradient in thin films sampling method (DGT) with a CeO₂/ZrO₂ mixed binding gel was developed for measurement of As(Ⅲ) and As(Ⅴ) in water and sediment. New CeO₂/ZrO₂ binding gel showed efficient adsorption toward As(Ⅲ) and As(Ⅴ) and was better than CeO₂ gel and ZrO₂ gels. The effective capacities of CeO₂/ZrO₂-DGT for As(Ⅲ) and As(Ⅴ) were 77.8 μg and 58.1 μg per device, respectively. Solution pH and ionic strength had no effects on the uptake of As(Ⅲ) and As(Ⅴ) by CeO₂/ZrO₂-DGT. The masses of As(Ⅲ) and As(Ⅴ) accumulated by the DGT increased linearly with time (R²>0.99) up to 72 h for tap water and synthetic seawater samples. Limits of detection (LODs) of As(Ⅲ) and As(Ⅴ) by CeO₂/ZrO₂-DGT coupled with an on-line hydride generation atomic fluorescence spectrometry (HG-AFS) were 0.06 μg/L and 0.08 μg/L, respectively. The method was used for measuring As(Ⅲ) and As(Ⅴ) in surface and sediment of several reservoirs in Dalian. The measured concentrations of As(Ⅲ) and As(Ⅴ) were 0.13-0.14 μg/L and 0.20-0.25 μg/L in the surface water and 0.38-1.82 μg/L and 0.69-3.46 μg/L in sediment.
