Abstract

The current study used an electromembrane extraction (EME) method to extract Cadmium from aqueous solutions. A supported liquid membrane (SLM) connected two glass chambers in a novel electrochemical cell design. The supported liquid membrane comprises a carrier and a polypropylene flat membrane impregnated with 1-octanol. Stainless steel and graphite plates were utilized as the anode and cathode, respectively. Cadmium was forced to travel through SLM during the removal process, which was done using an electric field. Effective parameters were examined with an interpretation of their influence on the removal efficiency of cadmium, including the kind of carrier, applied voltage, initial pH of the donor, and initial concentration of cadmium. Tris(2-ethylhexyl) phosphate (TEHP) and bis(2-ethylhexyl) phosphate (DEHP) were the two carriers that were employed. Based on the results, the applied voltage is the main factor that raises the cadmium mass rate across the membrane. Under ideal circumstances, 1.0 % v/v bis(2-ethylhexyl) phosphate in 1-octanol, 60 V applied voltage, pH of 5, initial cadmium level of 15 mg/L, 6 hours, and 1000 rpm stirring rate resulted in a removal efficacy of 90 %. The removal efficiency rose from 50 % at zero voltage to 90 % at 60 V in contrast with no voltage applied, confirming the potential use of EME in removing heavy metals.

期刊介绍： The Process Safety and Environmental Protection (PSEP) journal is a leading international publication that focuses on the publication of high-quality, original research papers in the field of engineering, specifically those related to the safety of industrial processes and environmental protection. The journal encourages submissions that present new developments in safety and environmental aspects, particularly those that show how research findings can be applied in process engineering design and practice. PSEP is particularly interested in research that brings fresh perspectives to established engineering principles, identifies unsolved problems, or suggests directions for future research. The journal also values contributions that push the boundaries of traditional engineering and welcomes multidisciplinary papers. PSEP's articles are abstracted and indexed by a range of databases and services, which helps to ensure that the journal's research is accessible and recognized in the academic and professional communities. These databases include ANTE, Chemical Abstracts, Chemical Hazards in Industry, Current Contents, Elsevier Engineering Information database, Pascal Francis, Web of Science, Scopus, Engineering Information Database EnCompass LIT (Elsevier), and INSPEC. This wide coverage facilitates the dissemination of the journal's content to a global audience interested in process safety and environmental engineering.
