In this study, 13X zeolite was successfully synthesized from natural local kaolins DD1, DD2 and DD3 via alkali fusion followed by hydrothermal treatment. Fusion with NaOH, followed by hydrothermal reaction, kaolinite and halloysite in kaolin sample were converted inton 13X zeolite. The Three kaolins DD1, DD2 and DD3 issued zeolite 13X were characterized using X-ray diffraction (XRD) and scanning electronic microscopy (MEB). The adsorption experiments were done using the real textile effluent. The results show that the adsorption is efficient and feasible at ambient temperature on DD1 kaolin issued 13X compared to 13X zeolite synthesised by DD2 and DD3 with good discolouration efficiency. Experiments with real textile wastewater showed an improvement of physico-chemical characteristics (COD, MIS,PO 4 3-, NO 2-) compared to the untreated effluent.
