Abstract
Heavy metals pollution becomes a serious environmental problem because heavy metals are non biodegradable and some heavy metal ion such as nickel is known as toxic metal. In this study, we investigated the natural sorbent materials for removing heavy metals nickel-ions in the wastewaters using carbon nanodots (C-Dots) from frying oil. C-Dots was resulted from frying oil by the hydrothermal method at temperature 300o C for 2 h. The results showed that C-Dots could remove heavy metal nickel-ions in the solution. Electric current from the solution of heavy metal nickel-ion decreases with the number of C-Dots and time that used in the process of removal. The intensity of adsorption spectra from nickel ions contained in the wavelength 600-800 nm. C-Dots from frying oil have a great potential as a natural sorbent.
4. Conclusion
In this preliminary study, for the first time, C-Dots from frying oil could remove heavy metal nickel-ions. The removal process of nickel-ions is strongly influenced by the amount of C-Dots and time process. Electrical and optical properties from the solution of heavy metal ions decreases with increasing the amount of C-Dots and the time process. Furthemore, C-Dots from frying oil have a great potential as a sorbent materials.
