The invention discloses a method for recovering titanium by centrifugal extraction from waste sulfuric acid of titanium dioxide. The method includes the steps that (1) by primary amine centrifugal extraction, extracting titanium from waste sulfuric acid. Extracting agent and waste sulfuric acid produced by sulfuric acid production of titanium dioxide conduct centrifugal extraction reaction; (2) dilute sulfuric acid single-stage wash a titanium rich organic phase. The titanium rich organic phase reached by centrifugal extraction reaction of step (1) conducting single-stage washing in a container with a mixing device, the washing solution is dilute sulfuric acid with mass concentration of 5-10%, and conducting stationary phase separation after single-stage washing; and (3) the titanium rich organic phase is centrifugal reversed extracting. The washed titanium rich organic phase reached by step (2) is mixed with alkali solution with concentration of 0.5-1mol/L, the titanium rich organic phase is reversed extracting, and titanium containing solution and blank organic phase are reached after the titanium rich organic phase is reversed extracting. The method for recovering titanium by centrifugal extraction from waste sulfuric acid of titanium dioxide need not synergistic extracting agent, and has lower cost; by adding the single phase washing process of the titanium rich organic phase, iron content in the titanium rich organic phase can be reduced; and the titanium rich organic phase is centrifugal reversed extracting through alkali solution, the reserve extracting time is short and the reserve extracting time is high.
