The various diatomite samples were tested for the removal of the methylene blue dye (MB)
in aqueous solution. Effect of some reaction parameters influencing adsorption was
studied. The application of models of the kinetics and adsorption equilibrium was detailed.
The adsorption test results showed the efficiency of the adsorbent employed for the MB
discoloration. In ultra-pure water, the maximum adsorbed quantity (Q
0
max ) of MB dye was
125.64 mg/g (for IGB04 sample) at 25 °C and pH 7.0.
The natural diatomite of the Irghbel site turns out to be formed in a deeper marine
environment; it is more silicified and therefore more interesting from an exploitation point
of view.
