Abstract
A study was conducted on the stoichiometry of the complex formed by th e extraction of aluminium ions by didodecyl naphthalene sulphonic acid (HDDNSA) from phosphoric acid solutions. The experimental results wer e analyzed numerically by non-linear regression. It was found that alu minium is extracted in the form of the complex ion AI(DDNSA)(3). The v alue of the equilibrium constant of the reaction was also calculated. (C) 1997 Elsevier Science B.V.
