Fig. 1 shows the effect of feed solution pH on the nickel extraction. Clearly, nickel extraction increases up to pH 10 and then decreases rapidly. This decrease can be explained by the formation of (Ni(NH 3) n 2, n = 6) which reduces the nickel extraction at higher pH values (Alguacil and Cobo, 1998, Kolhinen and Jalkanen, 2005).It has also …

In general, rinse water baths are used to remove the excess Ni and Au plating solutions, which still adhere to the electroplated parts. Excess solutions contain very small but economically significant quantities of precious metals viz. Ni 2+ and [Au(CN) 2] − ions. Owing to its outstanding physical and chemical properties, Ni is considered a highly …
