摘要
本文报道用新试剂2-(6-甲基-2-苯并噻唑偶氮)-5-二乙氨基酚(MBTAE)分光光度法测定微量镍。Ni:MBTAE=1:2,ε=8.1×104L/mol·cm,Ni2+浓度在0~22μg/25mL范围内服从比尔定律。用于金属有机化合物中微量镍的测定,结果与理论值相符。
This paper reports the spectrophotometric determination of mircoaamount of nickel by a new reagent 2-(6-methyl-2-benzothiazolylazo)-5-diethylamino phenol (MBTAE). The apparent molar absorptivity of the complex is 8.1×104L/mol.cm, and the composition is Ni:MBTAE=1:2. Its linear range is 0 ̄22μg/25mL. The method has been used to determinemicro amount of nickel in organo-metal and the result corresponds with the theoretical value.
