文摘

Aluminum scrap (AS) is utilized as an aluminum source to prepare zero-valent Al. HCl is the most effective acid to prepare acid-washed AS (AWAS) for bromate removal. Bromate removal from water by AWAS can be attributed to reduction and adsorption. Effects of temperature, pH, co-existing anions, particle size are investigated. Recyclability of AWAS is improved by acid-washing regeneration to reduce bromate.
