The paper investigated results effect of the conditions on absorbance of ZrXO, that: the optimal absorption wavelength was 535nm, the optimal concentration of H₂SO₄ was 0,35M, the volume ratio of 5.10^-3M Zr and 5.10^-3M XO was 5.0/5.2. Established a calibration curve to determine concentration of Zr(IV) at 535nm in the linear concentrations range from 10^-4 - 5.10^-3M. Research results effect on extraction efficiency of Zr(IV), including: with 0.35M H₂SO₄ for E = 72.27%; with V_o/V_a = 1/1, E = 72.27%; contact time of two phases and equilibrium separation time of two phases were 20 minutes, E = 72.27%; [Na₂SO₄]] = 0.25M, that the best effect on the extraction efficiency Zr(IV). Special, we introducted some characteristics of the extraction system Zr-H₂SO₄-CTAB, that were: built extraction isotherms of Zr(IV) at concentrations of (0.05-1.0M) H₂SO₄; according the Mc Cable-Thiele plot with V_o/V_a=1/1 the degrees of the theory extraction of Zr(IV) were 4 and V_o/V_a = 2/1 were 2; extracts 96.52% of Zr(IV) from Zr(IV) 5.10^-3M through 5 times extraction; loading organic (LO) of 10^-4M CTAB/CCl₄ was determined to be 0.4455 g/L Zr(IV) through 5 times of phases contact.
