摘要
Abstract
In order to recover Ni from acid leaching solution of waste oil refining catalyst,HBL110 was used as extractant to extract nickel directly and selectively.The saponification rate of extractant,extractant concentration and extraction equilibrium time were optimized,the extraction and de extraction stages were confirmed,and the multi-stage countercurrent series extraction simulation test and the continuous running of the on-line process were carried out.The results show that under the conditions of saponification rate of 40％,HBL110 concentration of 25％and extraction time of 10 min,the mass concentration of nickel in the raffinate is less than 30 mg/L,the extraction efficiency of nickel is more than 98％,and the extraction rate of Al and Fe is less than 3％.The three stage countercurrent extraction of nickel supported organic phase with 75 g/L sulfuric acid can achieve 100％back extraction of nickel supported organic phase.The on-line extraction process of the acid leaching solution of the waste catalyst is run continuously for 5 days,the nickel concentration in the raffinate is stable at 5 mg/L,and the extraction efficiency of nickel can reach 99％.The concentration of nickel in the back extraction solution is stable at 8 g/L,and the back extraction rate of nickel is 100％.The organic phase can be effectively recycled.关键词
