Zeolites are materials with very different characteristics are due to the absorption properties, ion exchange, and the ability of screening applications in various industries. Synthetic zeolite crystal purity and chemical due to natural zeolite with greater commercial importance, and this has led in the past two decades, many efforts are made to synthesize zeolite. There are several methods for the synthesis of zeolites, such as hydrothermal, microwave, sol–gel. In this paper, NaA type zeolite synthesized by ionothermal method with Ultrasonic Assisted have been done. To study the properties of the powder X–ray diffraction analysis (XRD), scanning electron microscopy (SEM) and FT–IR are used.The results showed that the crystal size is about 45–50 nm.<\div>

In this study the synthesis of graphite oxide and graphene via a low–cost manufacturing method. The process started with the chemical oxidation of commercial graphite powder into graphite oxide by modified weak base method, followed by the exfoliation of graphite oxide in distilled water using the ultrasound frequency from a laboratory ultrasonic bath. Finally, the oxygen functional groups on exfoliated graphite oxide or graphene oxide were eliminated by stirring in hot distilled water at 95∘C for 24 hr. The results assured that stirring in hot distilled water could give the product of graphene or reduced graphene oxide. The samples were characterized by FTIR, XRD, UV–Vis and SEM methods.<\div>
