✦ Synopsis

Proton adsorption isotherms derived from potentiometric titration of high surface area alpha aluminas were deconvoluted to yield proton affinity distributions. The results reported provide another view and additional support to the conclusion reached by Mao and Vanmce [ Appl. Catal. A, 111 ( 1994) 1511 that these materials prepared by topotactic transformation of diaspore have surface properties unlike those of either low surface area (Y-A&O~ or transition aluminas.

Aluminium dross tailings (ADT), a chemical waste from a factory producing aluminium in Egypt, was used for the recovery of the aluminium content in the form of alumina (Al 2 O 3 ). Extraction of the aluminium was carried out via atmospheric-and high-pressure leaching with caustic soda. Then, it was
