Abstract
A systematic study of acid treatment influence on sepiolite properties has been started. So that, sepiolite was treated with HCL, at 25ºC, modifyning acid concentration and time of treatment. Afterwards, free silica was removed and measued. Solids obtained after both acid treatment and after free silica removal were systematically characterized by X-ray diffraction and thermal analysis, studying the changes observed in their behaviour.
