    Abstract: Clay materials have been used for centuries by local populations in ceramic pottery. This research aimed to examine natural clay as raw material for the manufacturing of ceramic pot filters. Thus, three clay samples were collected from a quarry in “Sè”, located in the southwestern part of the Benin Republic. All the samples were characterized using... Show More

    Abstract: The first time water solubility derivates of chitosan Bombyx mori was obtain. By FTIR method it was established the fact of formation of chitosan succinate. Influence of synthesis condition to structure of chitosan succinate was shown. It is revealed that, gel formation of chitosan succinate depend on the formation of both polyelectrolytic complex ...
