Abstract

     The adsorption processes often constitute a complementary technique to the sector of conventional drinking water in order to eliminate the organic substances [1]. Taking into account the disadvantages met at the time of the placement of the activated carbon, it appeared interesting to us to study the adsorption of the organic pollutants on bentonite and on Al13. After the knowledge of the characteristics of this clay largely produced in Algeria, and of the Al13 produces at the laboratory, our tests were related to phenolic solutions, of whose absorbance was determined by UV [3-4]. We were then brought to evaluate the influence of reactional parameters [1-4] such as adsorbent masses and adsorbed mass, and the pH on the output of phenols elimination in distilled water solution. It appeared that an optimal amount of bentonite and Al13 could be given for a given content of phenol. In the same way, the pH seemed to conditionate strongly the effectiveness of the phenols adsorption by the surface of bentonite and Al13.
