Abstract：The adsorption behavior of Ni(Ⅱ) on potassium tetratitanate whisker was studied systemically by FAAS, seeing about the reasons for absorption, disentanglement and the effect of interfering ions on the recovery. The preconcentration method was simple, quick and had good selectivity. The adsorption rate of Ni(Ⅱ) by potassium tetratitanate whisker was 100% at pH 5.0 and Ni(Ⅱ) could be eluted from potassium tetratitanate whisker with hydrochloric acid (C: 0.5 mol·L-1), shake time exceeding 5 min，stick time exceeding 1.5 h, and the disentanglement ratio exceeding 90%. The relative standard deviation (RSD) was 2.6%. The results obtained indicate that the potassium tetratitanate whisker has good regenerate capability.
