Abstract
An arsenic compound solution, and an albumin nanoparticle and a lyophilized preparation prepared using same and entrapping an arsenic compound. The arsenic compound solution is prepared using the following method: adding AsOpowder in sterile deionized water to obtain a suspension, 6 to 25 mg of AsOpowder being added in every mL of sterile deionized water; dripping an NaOH solution to the obtained suspension until the powder is fully dissolved and adjusting the pH of the solution to 7.5 to 9, and making the concentration of the obtained arsenic compound solution be 5 to 20 mg/mL in terms of the added AsO. The albumin nanoparticle is prepared by mixing an albumin solution and the arsenic solution and the arsenic solution with the mass ratio of the added AsOin arsenic compound solution to the albumin ranging from 1:5 to 1:20 and using a method of solvent removing and physical curing.
