摘要
本文详细地研究了新显色剂4-(2-苯并噻唑偶氮)焦酚与Ti(Ⅳ)和CTMAB的灵敏显色反应和所形成的配合物,该配合物的λ_max=580nm,表观摩尔吸光系数为7.01×10 ̄4。钛在0~18μg/25ml范围内服从比尔定律。
It is reported in this paper that 4-(2-benzothiazolylazo)pyrogallol(BTAPG),a neworganic reagent,reacts with Ti(Ⅳ)to form a stable complex in the presence of CTMAB.Its λ_max is580nm,ε is 7.10×10~4.Beer″s law is obeyed in the concentration of Ti(Ⅳ)0-18μg/25ml.The proposedmethod has been applied to the spectrophotometric determination of microamount titanium in steel withsatisfactory results.
