Effect of pH on the extraction of malic and succinic acids

摘要：

A study was made on the extraction equilibria of malic acid and succinic acid from aqueous solutions using tri-n-octylamine (TOA) in 1-octanol. It was shown that the loading values of TOA decreased with increasing pH values in single component solution. On the other hand, the behavior in binary mixture was different with single component solution because of competitive reaction between malic acid and succinic acid.
