NOVELTY - Preparation of hydroxyl alumina ferric oxide composite adsorbent for removing arsenic in water, involves (1)weighing 0. 5 g of graphene oxide, adding 50-50 deionized water ultrasonic processing for 1 hour, (2) 0.25g of aluminium nitrate nonahydrate, 0.25g of ferrous sulphate heptahydrate is added to solution for further ultrasonic treatment for 30 minutes, (3) Gradually adding 2 mol/L of ammonia water solution and 2 mol/L of sodium hydroxide solution to solution, adjusting the pH value of the solution to 5.5-6.0, and continuously stirring to form precipitate (4)transferring the obtained precipitate to the high pressure kettle, placing for 10 hours at 180 degrees Celsius, (5)Collecting residue in high pressure kettle, deionized water cleaning, drying for 3 hours under condition of 60 degrees Celsius, obtaining high-efficiency aluminium base and iron-based composite adsorbent. USE - Preparation of hydroxyl alumina ferric oxide composite adsorbent for removing arsenic in water. ADVANTAGE - The composite adsorbent of aluminum oxyhydroxide and iron oxide has good stability, high adsorption efficiency, low manufacturing cost, environmental protection, recyclability.
