2.The concentration of scandium was directly proportional to the second-order derivative oxidation peak current of the Sc(Ⅲ)-ALC complex over a range of 2.0×10~(-9)～6.0×10~(-7) mol/L.
3.The influences of ICP-AES measure conditions and the matrix effect on intensity of spectral line of scandium are systematically studied. Yttrium is employed as an internal standard element and the analytical line pair (Sc 361.384/ Y 361 .105 nm) is chosen.
4.The separation of Sc(Ⅲ),Al(Ⅲ),Ti(Ⅵ),Mg(Ⅱ),Mn(Ⅱ),Y(Ⅲ) and Yb(Ⅲ) from sulfuric acid aqueous solution by the extraction method with 1,10 (1 pheny1 3 methy1 5 oxopyrazo 4 y1)decane 1,10 dione has been investigated, and a new method has developed for determining the micro constituent scandium.
