| description | <abstract language="eng">The present study consists in evaluating the NaX zeolite efficiency in removing Cu2+ from aqueous solutions, for future use of NaX in removing metals from wastewaters. The experiments were performed in batch systems (with shaking and continous stirring) and for different time intervals (1 to 24 h). Three particle sizes were employed: < 850 µm, 850 µm - 1 mm and 3 mm. It has been concluded that it is possible to employ the NaX zeolite for metal removal and the particle size plays an important role in the adsorption process. Specifically, NaX zeolites of smaller particle size achieved the maximum adsorption capacity of 152.36 mg of Cu2+/g of zeolite at pH = 4.5. |
