硫酸介质中P_(538)萃取Fe(Ⅲ)、Al(Ⅲ)和Ga(Ⅲ)的研究

Study of Extraction Separation of Fe(Ⅲ ), Al(Ⅲ)and Ga(Ⅲ ) with P_538 in Sulfric Acid Wedia

本文研究了在硫酸介质中酸度、萃取剂浓度,温度、协萃剂等因素对P_(638)萃取Fe(Ⅲ)、A1(Ⅲ)和Ga(Ⅲ)的影响.

Abstract The extraction behavior of Fe(Ⅲ),Al(Ⅲ),Ga(Ⅲ)with P538 in kerosene in sulfric acid media were studied. Effects of concentrations of P538, temperature, synergic reagent were investigated. Results indicate that extraction of the three metals ions is in the order:Fe(Ⅲ) >Ga(Ⅲ)>Al(Ⅲ) , Ga(Ⅲ) snd Al(Ⅲ) are separated with 0.3M P538 at 25℃,and Fe(Ⅲ)and Ga(Ⅲ) are separated with 0.15M P538 at 25℃, Addition of TBP results in negative synergism.
