Abstract
In this research, a urea-based porous organic polymer with a metal- organic framework (UiO-66-NH2), is investigated as an adsorbent for extraction of uranium from the aqueous samples. Affecting parameters on extraction efficiency such as pH of the sample solution, amount of adsorbent, sonication time, volume of eluent, sample volume and desorption time were studied. The limit of detection (LOD) was 0.6 μgL-1. The intra-day and interday precisions (RSD%) were assessed by five measurements at the concentration of 100 μgL-1. The intra-day and inter-day precisions were found to be 4.8% and 1.9%, respectively. The simple preparation of the sorbent, highly efficient, and fast separation provide a practical method for application of such material in industry.
