摘要：

The electrochemical method was applied to determine Sn(IV)/Sn(II) molar ratio in negatively charged colloid which forms in bronze plating sulphate solution containing laprol 2402C as a surface-active substance. An analysis of characteristic voltammetric minimum the onset of which is highly sensitive to Sn2+ concentration was used for this purpose. The Sn(IV)/Sn(II) ratio was found to be constant for completely formed colloid and independent on Cu(II) concentration in the solution. Particles involving Sn(IV) are supposed to be the main component responsible for stability of the sol. (C) 2002 Elsevier Science B.V. All rights reserved.
