摘要
在乙酸缓冲溶液（pH5．5～5．8）中，铝与铬天青S生成稳定的紫红色络合物。在545nm处，铝在0～50μg／100mL符合比耳定律，回收率在98％～104％之间．本法对钼精矿中铝的测定达到了满意的结果．
The red-purple stability complex of aluminium and chrome azurol S (CAS) can be formed in the medium of acetiate buffer solution (pH 5. 5~5. 8). The complex exhibits maximum absorption at 545nm. Beer's law is obeyed in the range of 0~50μg Al/100mL, and the recovery is 98%~104%. The method used for determination of aluminium in molybdenum concentrates with satisfactory results.
