Available in PDF, EPUB and Kindle. Book excerpt: "Emulsion liquid membrane (ELM) technique is a modified technique that combines the traditional solvent extraction and stripping in a single unit operation. The characteristics of ELM include the large interfacial area and high selectivity when treating heavy metal ions. Through the study of applying ELM technique in extracting and stripping copper and nickel from single cation bearing solutions, this thesis targets at the extraction and separation of different metal ions including copper, nickel and calcium from a synthetic wastewater stream by using the minimum reagent and energy consumption. A two-stage mixer-settler was eventually built-up and implemented to test the extraction and separation efficiency of ELM.As for copper extraction, the extractant used was LIX 984N, four factors were screened out as important ones: extractant concentration; W/O/W emulsion stirring time; W/O/W emulsion stirring speed; and CuSO4 solution/emulsion volume ratio. The other factors were not important thus they were fixed at constant value. The optimum operating condition of copper extraction is determined to be: CuSO4 solution/primary emulsion volume ratio of 3.2; extractant concentration of 6.7 wt %; H2SO4 concentration of 4.6 mol/L; W/O/W emulsion stirring time of 24 minutes; and W/O/W emulsion stirring speed of 415 rpm (1 rpm = 1/60 Hz=[pi]/30 rad/s). As for nickel extraction, the extractant used was Cyanex 301, the optimum laboratory conditions were: extractant concentration of 7.2 wt %; stripping solution (H2SO4) concentration of 0.5 mol/L; NiSO4 solution pH of 4.5; and NiSO4 solution/emulsion volume ratio of 3.5. A series of comparison tests between ELM technique and traditional solvent extraction technique were performed and the following results were found: The loading capacity tests showed that emulsion phase had a higher nickel extraction capacity (8.128 g Ni (II)/100 g Cyanex 301) than the organic phase (5.240 g Ni (II)/100 g Cyanex 301). The kinetics tests showed that the emulsion phase and the organic phase had a mass transfer coefficient of 2.823 × 10-7 (m/s) and 3.192 × 10-7 (m/s) respectively. After the process optimization and chemical characteristics have been explored for ELM treating copper and nickel ions separately, the selective extraction and separation of copper and nickel from calcium ion in a synthetic wastewater solution mimicking the nickel mine tailings from Sudbury, Ontario was investigated. The solution had a copper concentration of 10 ppm, nickel concentration of 20 ppm; an averaged calcium concentration of 250 ppm and its pH was 4.0. Two stages were implemented. In the first stage, LIX 984N was used as copper extractant, the optimum operating conditions were: extractant concentration of 0.97 wt %, H2SO4 concentration of 0.5 mol/L, W/O/W emulsion stirring time of 22.5 minutes and synthetic solution/emulsion volume ratio of 4.0. The copper removal rate was 96.7% while nickel and calcium removal rate was only 0.9 % and 1.3%; In the second stage, a mixture of LIX 984N and Cyanex 301 at a volume ratio of 1 to 1 was used as extractant, and the optimum operating conditions were: extractant concentration of 6.7 wt %, H2SO4 concentration of 5.7 mol/L, W/O/W emulsion stirring time of 25 minutes and synthetic solution/emulsion volume ratio of 3.5. The nickel removal rate was 99.0% while the calcium removal rate was 0.55%. A two-stage bench-scale mixer-settler proved the process of using ELM to extract and separate these metal ions was successful under these optimum conditions obtained." --
