HG/T 3927-2007

Industrial activated alumina

[Application] Activated alumina is mostly used in chemical catalysis, and its application in water treatment is currently introduced to remove fluorine in water, and it can also remove organic matter, phosphate , and sulfate ions in water

The defluoridation effect of activated alumina is shown in Table 4-23

Li Shuyou and others studied the removal of arsenic by activated alumina, and the results showed that the mechanism of arsenic removal is mainly adsorption, and the efficiency of removing As ⁵⁺ is significantly higher than that of As ³⁺ , as shown in Table 4-25
