- Determination of the brightener adsorbed during the electrodeposition of Sn-Ni alloy from acidic chloride bath.
説明
In a previous paper reference, it was reported that mirror bright electrodeposits of tin-nickel alloy were obtained from an acidic chloride bath containing N-(1-naphthyl) ethylenediamine dihydrochloride (NEDA) as brightener. In this paper, a spectrophotometric method for the determination of NEDA adsorbed in the alloy is established.<br>In order to keep the structure of the brightener intact, the alloy deposits were dissolved in dilute hydrochloric acid which was used in the plating bath, at 60-65°C. The color development is based on the coupling reaction of NEDA with the diazonium salt of sulfanilamide to form an azo compound, which has an absorption maximum at 540nm. Although tin (II) dissolved from the alloy reacted with the diazonium salt, greatly inhibiting the color phenomenon, this could be masked effectively with SbCl3 solution. The calibration curve for NEDA was rectilinear in the range of 0-400μg/100mL. The precision of analytical values was good, and the coefficients of variation were less than 1% (n=8).
