| Abstract | ||||
| Phosphogypsum (PG) is an important industrial by-product derived from phosphoric acid and phosphate fertilizer manufactures by dehydrates process. Using Saccharomyces cerevisiae as a biosorbant for uranium (U), thorium(Th) and radium (Ra) from (PG) by Appling different carbon sources such as maltose, sucrose, starch, lactose, fructose and glucose. Starch, maltose and fructose media give most uranium biosorption capacity (13, 13 and 14 ppm) while in sucrose and glucose media give (20 and 22 ppm). Maltose and starch media give the highest thorium biosorption capacity. At the same time sucrose and glucose give moderate biosorption. | ||||
