Summary  

An extraction chromatography method was developed for the separation of   239Np from 243Am in nitric acid solution. A sorbent based on aliphatic quaternary amine Aliquat-336 and hydrophobized silica gel was prepared. 239Np reduced to the oxidation state(IV) with ferrous sulfamate in 2M or 6M HNO3 sorbs on the prepared silica gel column. After washing with 0.1M ferrous sulfamate in 2.5M HNO3, 239Np is eluted with 0.1M HNO3 containing 0.02M HF. The separation of 243Am from 239Np is very effective. The purity of 239Np was found to be better than 99.5%. The proposed 239Np milking procedure is suitable for the preparation of 239Np tracer that can be used for the determination of 237Np radiochemical yield.
