Complexation of scandium 2-hydroxy-5-T-butylphenol-4-metoxyazobenzene (HR) was studied by atomic-absorption and spectrophotometric methods. Optimum conditions of formation and extraction of the complex were found. Maximum light absorbance of a complex in n-butanol is in the range of 470÷480 nm. Molar absorption coefficient equals to (2.2–3.0).104. Stability constant of scandium in n-butanol is л=2.8·1010. Selective and sensitive techniques of extraction-atomic absorption determination of scandium in soils were developed
