摘要
A sensitive,selective,rapid,simple,and convenient method for the determination of thorium was developed.The method was based on the color reaction of thorium with DBF-arsenazo in a strong acidic medium (4 mol/L HCI).The flow-injection technique was used with an automated flow- injection analyzer.Beer's law was obeyed in the range of 0—1.4 μg/mL.The relative standard deviations were less than 1%.
