The work presented in this paper is based on three main axes:  The first theme focuses on determining the structure of a new family of insecticidal pyrethroids - C21H16N2O4FClBr2 - from a spectrum of X-ray diffraction. ...

Textile dyes are classified as refractory organic compounds and non-biodegradable. They represent a potential danger to humans and the environment. The need for new technologies, effective and energy efficient to reduce ...

This study was devoted to the promotion of a lignocellulosic waste namely wood sawdust through a simple chemical functionalization in order to apply to the removal of anionic dyes. A comparative study was conducted on the ...

The aim of this work is study the degradation of a xanthene dye called "Erythrosine" (Er) in homogeneous and heterogeneous environments. In a homogeneous medium, discoloration and degradation of Er was carried out by ...

The polymers are less expensive and much usually in treatment of water. And from of these polymers: the cellulose which takes important place and his chemical structure. This polysaccharide is linear withdraw in his surface ...

Our study is based on the synthesis and the application of the membrane prepared from treated /non treated clay and starch at different volumes and concentrations. The best membranes found has been tested for their abilities ...

A simple technique (solvent phase inversion) has been used to prepare biodegradable polymeric membranes based on a mixture of clay (chemical treated, no treated) and starch. The disc samples of 100-300μm thickness were ...
