Screening of parameters and optimization of nickel extraction by green emulsion liquid membrane using statistical experimental design

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study focuses on the extraction of nickel ions from an aqueous solution using a green emulsion liquid membrane (GELM). Its primary objective is to choose between corn oil and sunflower oil as a solvent in GELM and compare their performance with a kerosene‐based emulsion liquid membrane (ELM).

Experimental methods in chemical engineering: Electron probe micro‐analysis—EPMA

The Canadian Journal of Chemical Engineering, EarlyView.
ABSTRACT Electron probe microanalysis (EPMA) is a non‐destructive spectroscopic technique to map the chemical composition—quantitative elemental distribution and layer thickness—with a micro‐scale resolution. An electron beam illuminates the surface of a sample and produces backscattered electrons (BSE), secondary electrons (SE), characteristic X‐rays,

Facing the Risk of Greenwashing in the ESG Report of Global Companies: The Importance of Life Cycle Thinking

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Accurate reporting on the sustainability of business value propositions must be supported by reliable data sources and sound methodologies such as life cycle assessment (LCA). Showing commitment to more responsible activity without quantifying business impacts, or quantifying them only partially, could fall into greenwashing practices.
