Abstract

Heavy metals have a high density, atomic weight, or atomic number. Heavy metals are potentially hazardous to health and the environment and must be separated. Emulsion liquid membrane is a promising technique to remove heavy metal contaminants from industrial and household effluents. Emulsion liquid membrane (ELM) is used to separate heavy metals as it is effective and efficient. ELM involves external, membrane, and internal phases. The internal phase is essential in the separation process as it carries stripping agents to pull metals from the membrane to the internal phase. The choice of stripping agent concentration in the internal phase, such as HNO3, H2SO4, HCl, NaOH, and Na2CO3, affects the extraction efficiency in separating heavying metals using ELM. This article evaluates the effect of stripping agent concentration on extraction efficiency.

Abstract

Growing industries and human activities have increased the amount of waste containing heavy metals, potentially toxic to human health and the environment. Conventional methods for handling heavy metal wastes have limitations, so the current emerging technique is emulsion liquid membrane (ELM), which is easy and inexpensive and leads to green chemistry. The composition of ELMs generally consists of surfactant, extractant, stripping agent, and diluent. In this article, the focus is on the use of environmentally sustainable diluents derived from vegetable oils. The diluent acts as a solvent for the extractant, helping form a stable emulsion and lowering the emulsion breakage percentage. This article aims to evaluate the potential use of vegetable oils as diluents in the Emulsion Liquid Membrane (ELM) process to improve emulsion stability and heavy metal extraction efficiency.
