Sugarcane straw ash (SCSA), an agricultural waste of sugar industry with disposal problems, was utilized as a source for the synthesis of zeolitic material. Zeolitic material was synthesized by alkali fusion followed by hydrothermal treatment. The effect of crystallization time was studied and the conditions optimized. The materials were characterized by XRD, XRF, SEM, FT-IR, Brunauer-Emmett-Teller (BET) surface area techniques, particle size analyzer, TG /DSC and nitrogen physisorption. The presence of zeolite NaP1 in adsorbent confirms successful conversion of native SCSA into zeolitic material. The physico-chemical properties of SCSA and zeolitic material were compared. The particle size distribution of zeolitic material was in the range of 0.796 – 399 µm and nitrogen adsorption indicated a surface area around 350 m2 g-1. Zeolitic material from sugarcane straw ash was examined by removal of Crystal violet from aqueous solution.
