In a research conducted to determine the effective parameters on nanofibers adsorbents, Iranian researchers from Islamic Azad University succeeded in designing and optimizaing modified acrylonitrile nanofibers to measure toxic heavy metals.
A simple, reliable, and selective method has been used in this research to rapidly detect tiny amounts of Cr3+ ions in aqueous samples through flame atomic adsorption spectrometry.
"In this research, the Cr3+ ion in the sample formed complexes with acrylonitrile nanofibers modified by methanolamine, and it was adsorbed. Then, it was stripped in low volume of heavy metal complex by an appropriate eluent. As a result, the heavy metal complex was doped a few times, and it was finally measured through atomic adsorption techniques and flame atomic adsorption spectrometry," Dr. Ali Moqimi, one of the researchers of the plan, stated.
The present method is a simple, reliable, and selective method to rapidly detect tiny amounts of Cr3+ ion in aqueous samples through flame atomic adsorption spectrometry. Measurement level reduced to 60pg mL-1 due to the use of pre-doping process, and the doping factor was equal to 100. The precision and accuracy of the presented method were compared with the results obtained from other standard methods.
Results of the research have been published in 2011 in E-Journal of Chemistry, vol. 8, issue 3. For more information about the details of the research, visit the full paper on pages 1052-1061 of the same journals.
