ABSTRACT:
The invention relates to a method for eliminating metal halides which are present in a liquid or gaseous, organic or non-organic effluent. According to the invention, the elimination is carried out by absorption of said metal halides on alumina agglomerates. The inventive method is characterised in that: the specific surface area of said agglomerates is between 50 and 350 m2/g, preferably between 70 and 300 m2/g and, better still, between 80 and 250 m2/g; and the V80Åthereof is greater than or equal to 20 ml/100 g, preferably greater than or equal to 25 ml/100 g, better still greater than or equal to 30 ml/100 g and, optimally, greater than or equal to 35 ml/100 g.
