The micellar solubilization spectrophotometry was used to determinate trace germanium(Ge) in grains. The samples were digested by refluent HNO 3 and the residue was dissolved by NaOH.The condition of this method was determined also. The results showed the method simple, high precision in Ge determination and the recovery coefficient ranged from 92.4% to 102.5%.
