Abstract
An efficient natural bioextractant, orange peel extractant, was applied to recover uranium as one of hazardous elements. Batch experiments were carried out to determine the effect of various factors on the uranium extraction using a synthetic standard solution. These factors include the diluent type, pH, solvent concentration, contact time, and temperature. Under the optimum conditions (pH 4, A/O = 3/1), the maximum saturation capacity of the orange peel extractant for uranium reaches approximately 54.5 mg/g. The extracted uranium ions were almost completely eluted with NaCl/H2SO4 (1 M each). The procedure was applied to real sulfate leach liquor of a clay stone sample from Southeastern Sinai, Egypt.
