Abstract:

The adsorption of Acid orange 7 (AO7) by Polypyrrole/nanosilica composite (PPN/SiO2) was studied and various parameters have been investigated, more than 99.4% of the adsorption efficiency was obtained under the optimal conditions (PPN/SiO2 mass = 1 g/L, contact time = 90 min, Initial AO7 concentration = 10 mg/L, shaking speed = 200 rpm and temperature = 328 K and pH = 3).PPN/SiO2specifications were determined using FTIR, XRD, TGA, pHzpc,TEM and SEM analysis....
