石煤提钒后液中钼的回收

用离子树脂交换法回收石煤提钒后液中的钼,首先通过树脂选择实验选出最佳树脂D314,然后用动态方法研究不同条件对D314树脂吸附性能的影响。结果表明在pH=3、吸附接触时间90 min、钼浓度10.24 g/L时,D314树脂对钼的吸附性能最好,工作吸附容量可达162.8 mg/mL,负钼树脂在解吸剂氨水浓度为12%、解吸时间90 min时,解吸效果较好。

Man from the Hauslabjoch

On September 19, 1991, at an altitude of 3,200 m (10,498 feet), the remains of a well-preserved, freeze-dried mummified body of a 3,000 BC, Late Stone Age man, was found on the Austrian-Italian border. Studies conducted at the University of Innsbruck have revealed that these are the remains of a 45-46-year-old male, 45 kg (99 lbs) (living weight) and 160 cm (5 feet, 2 inches) tall. Morphometric, pathophysiologic, paleobotanical, photogrammetric, anthropological, computer tomographic, and other studies have been conducted to determine the living conditions and possible causes of death of this Late Stone Age man.
