从含30g/L Ni(Ⅱ)和0.1—1.5g/L Bi(Ⅲ)的乙酸水溶液中,研究了用氢加压还原镍(Ⅱ)的机理和动力学。催化剂采用粉末状石墨和碳化钨。当采用碳化钨时,发现还原溶液中水溶铋(Ⅲ)的稳定性受到强烈限制。含铋
The mechanism and kinetics of nickel (Ⅱ) reduction by hydrogen are studied from 30% acetic acid aqueous solution containing 30 g / L Ni (Ⅱ) and 0.1-1.5 g / L Bi (Ⅲ). The catalyst is powdered graphite and tungsten carbide. When using tungsten carbide, it was found that the stability of water-soluble bismuth (III) in the reducing solution was strongly limited. Bismuth-containing
