Since their invention, ELMs have been employed for ,wastewater treatment, and metal recovery from residual aqueous solutions produced by galvanic plants or mine waters (Correia & Carvalho 2001; Park et al. 2004; Bahloul et al. 2015).ELMs have high interfacial areas of mass transfer due to the small size of the aqueous phase droplets, so the metal ions have a high diffusion rate through the membrane.

1/11/2020, · In the hydrochloric ,acid,/nitric ,acid, system, Pt/Pd can form the corresponding xanthate precipitate with xanthate. The xanthate solution is stable in the pH range of 6.5–7.5, but it partially decomposes into carbon disulfide and alcohol in acidic solutions (Cheng and Luo, 2016). The reaction equation is as follows: (88) ROCSS − + H + = CS 2 + ROH
