Abstract: The stainless-steel-washing  waste  solution  of  15-20  wt.% nitric acid, 5-10 wt.% fluoric acid, 1-1.5 wt.% Cr,  0.5-1.0  wt.% Ni and 2.8-3.0 wt.% Fe is treated by step-extracting  the  organic phase of Cr and nitric and fluoric acid at the phase rate of A/O = 2-5 with organic solvent of 30-50 vol.%  trioctylamine,  10  vol.% isodecanol and 40-60 vol.% kerosene from the waste soln.,  washing the organic phase with Na2CrO4 soln. at A/O = 1 to  remove  nitric and fluoric acid, getting Cr-concentrated water  phase  with  NaCl soln. at A/O = 0.2, recovering Na2CrO4  4H2O from the water  phase, recovering NiSO4 by the similar way.
