Yb and U were determined by removing the major interfering nuclide 82Br; Cu by 0.048mol/L NaDDTC/CHCl3 extraction from 1mol/L HCl medium; and As and P by using an inorganic exchange column of acid aluminum oxide(AAO). The interferences from fission products and γ spectrum of 235U have been corrected by the NAA software
