Quantification of additives in a watts nickel bath by the cyclic voltammetric stripping technique

The characterization of nickel deposits and quantification and optimisation of the various additives in a Watts bath can be done successfully using th e cyclic voltammetric stripping technique (CVS). This technique can be used as an on-line process which can be very helpful, for industry. This powerf ul analytical tool takes advantage of the polarisation effect. In this pape r an attempt has been made to study the effects of saccharin, butynediol, c oumarin on the deposit characteristics of nickel. CVS has been used to quan tify saccharin, butynediol, coumarin content in a standard Watts bath. The implementation of the CVS technique in areas such as PC board production ha s increased the process yield, decrease the downtime and decreased the usag e of excess of additive.
