 Abstract
The development of new materials with fly ash offers new scientific and technological perspectives due to the specific interesting physical properties of these materials. Adsorbents can be produced from waste materials containing Si and Al and lime. The utilization of adsorbents based on fly ash represents an alternative with ecological and economical implications because of reduction of pollution and the use of wastes. The authors present in this study the results of experimental researches on the adsorbents prepared in laboratory using fly ash produced at CET Holboca Iasi and lime from Bicaz. The conditions of obtaining are established and the characterization of synthesized materials is realized.

 Rezumat
Utilizarea de noi materiale pe bază de cenuşă oferă noi perspective ştiinţifice şi tehnologice cu privire la proprietăţile acestor materiale. Adsorbanţii pot fi obţinuţi din deşeuri care conţin Si şi Al şi var. Utilizarea adsorbanţilor pe bază de cenuşă reprezintă o alternativă cu implicaţii ecologice, în sensul reducerii poluării şi economice prin folosirea unor materiale reziduale. In această lucrare se prezintă rezultatele cercetărilor experimentale cu referire la sinteza de adsorbanţi pe bază de cenuşă rezultată la CET Holboca Iaşi şi var de Bicaz. Se stabilesc condiţiile de obţinere a noi adsorbanţi şi se realizează caracterizarea materialelor sintetizate.
