摘要:

The composition, stability constant and molar absorption coefficient of the chelate of scandium ion with Semi-Xylenol Orange (SXO) are determined speotrophotometrically in a medium of chloroacetate buffer. In the scandium-Semi-Xylenol Orange system, Sc(SXO) chelate is formed with a logarithmic stability constant of 19.66 and molar absorptivity of 2.4x104(530 nm) 1 mole−1cm−1.
