57 Name: ACTIVATED ALUMINA CAS No 1344-28-1 · — NAS/CWTC 027-82 Chemical Formula: A1203 xH2O Where x = approx. 0.4 Description: White, odorless, insoluble granules. Use: Used to remove arsenic, fluoride, and selenium. Purity Requirements: Analyses of available grades of activated alumina show the presence of chromium but at levels far below that which would necessitate RMIC values based on a maximum use of 2 g/liter of water. If analyses are desired, the following protocol is recommended. Bulk Sample Collection: Sample in accordance with Standard for Granular Activated Carbon, AWWA B604-74, American Water Works Association, Denver, Colorado (1974). Analytical Sample Preparation: Extraction Solution--Add 47 ml of 0.1 N sodium hydroxide to 100 ml of 0.1 M potassium hydrogen phthlate and dilute with deionized water to 200 ml. me resultant solution will have a pH of 5 + 0.05. amid e Prenaration--Grind sample to fit through a 40-mesh screen. Weigh 5 g of sample into a 400-ml beaker and add 200 ml of extraction solution. Add 1 drop of nonionic
