Tripathy, B.C., Das, S.C., Singh, P. and Hefter, G. (1999) Effects of perfluorocarboxylic acids during zinc electrowinning from acidic sulphate solutions. Bulletin of Electrochemistry, 15 (9-10). pp. 340-342.
In the present study the effects of perfluoro surfactants like perfluorobutyric acid (PFBA), tridecafluoroheptanoic acid (TDFHA) and pentadecafluoroctanoic acid (PDFOA) on zinc electrowinning from acidic sulphate solutions were observed. The results were compared with that of glue which is a tetraalkylammonium compound. It is found that these perfluoro surfactants are better leveling agents than glue with respect to current efficiency (CE), power consumption (PC), crystallographic orientations and surface morphologies of the zinc deposits.
