The purpose of this study wasthe characterization of granite sludgeand zeolite production fromIsfahanstone cutting factories. Granite sludge characterization was performed using X-ray diffraction (XRD) and X-ray fluorescence(XRF) analysis. The results of XRF analysis showed that granite sludge contains silica (%50.7), and aluminum (%16.9). For synthesis of zeolite, the alkali fusion method was conducted during hydrothermal treatment, taking into account the various parameters including the ratio of sodium hydroxide to granite sludge (1:1.2), temperature and residence time in the oven (400, 500 and 600 o C, 2 h), duration of aging time (24 h), hydrothermal time and temperature (90 o C, 6 h). For characterization of synthesized zeolites, different analysis such as scanning electron microscopy analysis (SEM), fourier transform infrared reflection (FT-IR), surface area (BET), and X-ray diffraction (XRD), cation exchange capacity (CEC), energy dispersive X-ray spectroscopy (EDX) and cadmium sorption were used. The results of the XRD analysis were evaluatedin qualitative and quantitative aspects. According to the qualitativeanalysis, the synthesized zeolites were Na-X and A type with different percentages. The results ofthe synthesis ofzeolitesat different temperaturesbyquantitative analysiswereas follows: synthesized zeolites at 600 o were (84% NaX and 16% A), at 500° were (91% NaX and 9% A) and at 400 o were (94% NaX and 6% A). Therefore, according to theresults, theoptimaltemperaturefor the synthesis ofzeolitesNaX, was considered 400°C.The surface area for sludge granite and zeolite were respectively 3.838 and 338.596 m 2 /g. The amount of CEC for raw materialand zeolite were 12.59 and 248.9 cmol/kg, respectively. The sorption of cadmium by synthesized zeolite in 1,5,10 and 100 mg/L concentrations at pH=6 showed thatthe sorption increased from75.4% to 94%with decrease of concentration.The sorption test showed that the synthesised zeolite has high efficiency for cadmium removal.Generally, the production of zeolite from granite sludge with attention to the economic aspects could be considered as a suitable method for management of this waste in stone cutting industry.
