Abstract

Effects of organic carboyl compounds on brightening and electrochemical behavior were studied in the electrodeposion of tin from acid sulfate bath. Electrochemical polarization measurements, potential sweep voltammetry and scanning microscopy were applied. Among the compounds examined, benzalacetone was the best additive for the brightener, and its adsorption on electrode in an acidic solution was ascertained through cyclic voltammetry.
