Adsorption of Cadmium(II) from Sample Water by Using Magnetic Acrylamide Nanocomposite
The removal of Cd(II) ions was investigated from various samples of water employing magnetic acrylamide nanocomposite. The effects of magnetic acrylamide nanocomposite dosage, pH extraction, and contact time on Cd(II) removal from sample water were monitored using spectrometry. In addition, adsorption isotherm models for the sorption of Cd(II) were studied in this research. The adsorption capacity of magnetic acrylamide nanocomposite for Cd(II) was achieved at 18.64 mg/g. The removal of Cd(II) using magnetic acrylamide nanocomposite was fitted with the model of the Freundlich isotherm. This removal process provides a value coefficient (R2 = 0.98) for Cd2+ ions and a very excellent linear range of 0.4–22 mg/L. By using a signal-to-noise ratio of 3 (limit of detection, LOD = 2.04 μg/L), the LODs for Cd2+ ions adsorption by magnetic acrylamide nanocomposite were attained. According to these results, magnetic acrylamide nanocomposite is a suitable adsorbent for removing Cd(II) from various water samples.
