【摘要】 采用硝酸再生大孔弱酸性阳离子交换树脂回收镍 D113树脂经再生—转型模拟循环加速试验,测其因周期性体积变化而导致疲劳裂球的性能,裂球率为8%,回收的硝酸镍可用于生产,表明此方法有良好的经济效益与环境效益更多还原

【Abstract】 The paper presents a method for recovering nickel with macroporous weak acid cation-exchange resins by the nitric acid regenerant. The resins is tested by rebirth-transformation to measure the fatigue crack of the resin beads due to periodic volume fluctuation. The collected nitric acid can be used in production. The results show that this method has good economic performance and environment beneficial result.更多还原
