In this study, metal-organic frameworks containing zirconium was successfully synthesized at soft conditions (temperature 25oC and ambient pressure). UiO-66 samples were characterized by XRD, FTIR, SEM, EDX and BET. The SEM-image result showed UiO-66 particles size of 100-200 nm. UiO-66 sample showed the high surface area (1436 m2/g) and high pore volume (0.707 cm3/g). The UiO-66 samples tested were used as an adsorbent to remove aquatic arsenic contamination. UiO-66 materials has a high ability to remove arsenic, reaching 78.82 %. The UiO-66 adsorbent functions excellently across a broad pH range of 1 to 11 and achieves a remarkable arsenate uptake capacity of 294.12 mg/g.
