The present paper deals with the separation of chloride, bromide, iodide, and thio-cyanate ions by the circular paper chromatographic method (Giri). Two series of eluents have been tested. One is the mixture of n-butanol, acetone, and ammonium hydroaide (3:13:4);the concentration of the latter can be 1.5, 3, 6, 9, 12 or 15 N. Good separation can be achieved with Hsin-Hua(新华)No.1 "Fast" filter paper and What-man No. 1 filter paper when the anions mentioned were chromatographed either singly or admixed. It has been found experimentally that the R_fc values of these anions were not greatly influenced by the basicity of the solvent as shown in Table 1 in the Chinese text. This solvent system is a modification of that used by Shoichi Nakano^[2].
