Measurements of the extraction equilibria of copper and zinc with N-8-quinolsulfonamides dissolved in toluene were carried out at 303 K.
It was found that the extractants (HR) exist as monomers and that copper and zinc (M) form a complex of an MR2 type in toluene diluent with HR.
Frorti the experimental results, it is seen that extraction constants of alkaryl-substituted N-8-quinolylsulfonamides are larger than those of alkyl-substituted N-8-quinolylsulfonaniides.
