The activity of Pd catalysts, synthesized by microwave assisted polyol method on carbon support, has been examined for formic acid electro-oxidation reaction. The catalysts were characterized with XRD to identify their nanostructure properties. The

Leaching time, stirring speed, temperature, hydrochloric acid concentration and hydrogen peroxide concentration were chosen as parameters. The optimum conditions for dissolution were
Author: Tevfik AĞAÇAYAK, Ali ARAS Publishing Date: 2017 E-ISSN: 2147-9364 Volume: 5 Issue: 3 ABSTRACT: In this study, dissolution kinetics of nickel from Gördes (Manisa-Turkey) lateritic ore by sodium fluoride in sulphuric acid solution was investigated. The effects of stirring speed, sulphuric acid concentration, sodium fluoride concentration and temperature on nickel extraction were examined. To determine the dissolution kinetics of nickel
