Nickel Removal from Exhausted Electroplatting Baths by Using Vegetable Wastes
نویسندگان
چکیده
During the last years our research group has been studying the use of industrial vegetable wastes as grape stalks and exhausted coffee to remove metals ions such as Ni(II), Cu(II), Pb(II), Zn(II), Cd(II) or Cr(VI) and Cr(III) in aqueous solution from the point of view to use these wastes as biosorbents in a low cost alternative to activated carbon for wastewater treatment. The optimal experimental conditions for the removal of each of these metal ions in synthetic solutions by using both biosorbents were determined in previous studies [Villaescusa et al. 2004; Martínez et al. 2006; Valderrama et al. 2010.]. In this work, the performance of grape stalks and exhausted coffee for the removal of nickel ions from an exhausted electroplating bath of a metal finishing industry from Barcelona (Spain) has been investigated.

Kinetic Study of Electrochemical Deposition of Nickel from Chloride Baths in the Presence of Saccharin
Nickel is an essential engineering material and electrodeposited Ni has been widely used in many fields to improve surface finishing, corrosion resistance and wear properties. The kinetics of electrochemical deposition of nickel from chloride baths in the presence and absence of saccharin on the copper substrate was investigated by applying cyclic voltammetry and chronoamperometry measureme...
متن کاملProlonging the Life of Electroless Nickel Plating Baths by Phosphite Removal
Electroless nickel plating baths have to be discarded when levels of phosphites build up and interfere with the plating process. OWMC funded research conducted at ORTECH International to determine whether phosphites could be removed from plating bath solution. The first attempt to do this by adsorption on flyash was unsuccessful. However, the use of calcium ion to precipitate calcium phosphite ...
متن کاملZinc recovery and waste sludge minimization from chromium passivation baths.
This work reports the feasibility of applying emulsion pertraction technology (EPT) aiming at zinc recovery and waste minimization in the zinc electroplating processes that include Cr (III) passivation. The assessment consists of firstly the lifetime extension of the passivation baths by selective removal of the tramp ions zinc and iron, and secondly, the recovery of zinc for further reuse. Spe...

Adsorption of phenol on acid-treated slag wastes in waste water
This study investigates the liquid-phase adsorption behavior of phenol form waste water by using slag, which is one of the solid wastes from steel refining process. This adsorption technique is one green process based on using the slag waste as adsorber for removing organic contaminants from waste water. First, the raw slag was chemically treated by different concentrations of sulfuric acid, an...
