This paper presents a synthesis of mesoporous silica (MS) from natural clay as silica sourceusing L35 pluronic(EO11PO16EO11) as structure directing agent. The prepared material wascharacterised by XRD, FRX, TGA, SEM, MET and N2 adsorption-desorption analyses. Then,mesoporous material was used for the removal of Acid Red 337 (AR337) from aqueous solution, and the treatment of real textile effluent. The effect of pH, contact time, weight of adsorbent and initial concentration wasstudied in batch adsorption. The synthesizedmesoporous material showed good discolouration efficiency with a 62% percentage. Experiment with real textile wastewater showed that 39%, 40% and 31.2% of thecolor, TOC and CODrespectively were eliminated byusing 1g of MS per litre of wastewater.
