Tin anode slime is a by-product of the tin electrolytic refining process. This study investigated a route to separate Sn, Sb, Bi, and Cu from tin anode slime after leaching with hydrochloric acid. In the solvent extraction process with tributyl phosphate, Sb and Sn were extracted into the organic phase. Bi and Cu were unextracted and remained in the liquid phase. In the stripping experiment, Sb and Sn were stripped and separated with HCl and HNO3. Bi and Cu in the aqueous phase were also separated with chemical precipitation procedure by controlling pH value. The purities of Sn, Sb, Cu solution and the Bi-containing solid were 96.25%, 83.65%, 97.51%, and 92.1%. The recovery rates of Sn, Sb, Cu, and Bi were 76.2%, 67.1%, and 96.2% and 92.4%.

Abstract This paper reports a new method for the determination of aromatic amines with temperature-controlled ionic liquid dispersive liquid-phase microextraction in combination with HPLC and results of investigation of the influence of anions in ionic liquids on the extraction performance. In these experiments, 1-octyl-3-methylimidazolium hexafluorophosphate ([C8MIM][PF6]), 1-octyl-3-methylimidazolium bis (trifluoromethanesulfonyl) imide ([C8MIM][NTf2]), and 1-octyl-3-methylimidazolium tetrafluoroborate ([C8MIM][BF4]) were used as the extraction solvents for the investigation of the effect of anions in ionic liquids. Other parameters affecting the microextraction performance were also investigated. Under the optimal conditions, the proposed method had good linearity over the concentration ranges of 1.0–100 μg/L for 2, 4-dimethylaniline, 2-chloroanline, and N,N-dimethylaniline, and 1.5–150 μg/L for N,N-dimethylaniline and alpha-naphthylamine, with excellent correlation coefficients (R2 ≥ 0.999), excellent detection sensitivity with LODs (S/N = 3) in the range of 0.39–0.63 μg/L, and precision in the range of 3.2–5.4% RSD (n = 6). Real water samples were analyzed with the established method, and good spike recoveries in the range of 86.3 to 98.9% were obtained. These results indicated that this method would be useful in the routine analysis of such pollutants.

In this work we examined the industrial scale extraction process of ultra-low sulfur diesel with the help of simulation software ASPEN Plus®. This work focuses on the [Cnmim] [BF4] (imidazolium-based) ionic liquid and employed it in the extractive desulfurization of the dibenzothiophene (DBT) from the model diesel fuel under a very mild process condition. UNIFAC (uniquasi functional activity) was chosen as the thermodynamic method to model the ionic liquid on ASPEN Plus® and different physical and chemical properties were then taken from the literature to be incorporated in the simulation model. Different parametric analysis was studied for the removal of thiophene-based compounds from the model diesel. The results acquired shows the significance of imidazolium-based ionic liquids (ILs) for the extraction of S-contents from the liquid fuels at an optimal process conditions of 40 ℃ and 2 bar pressure with the 2.8: 1 ratio of ionic liquid and model diesel which validates the experimental results obtained previously in the literature.
