The exponential growth of electric and hybrid vehicles in the last five years forecasts a waste
problem when their batteries achieve end-of-life. Li-ion batteries for vehicles have been …

Water contamination with harmful arsenic compounds represents one of the most serious
calamities of the last two centuries. Natural occurrence of the toxic metal has been revealed …

Publisher Summary This chapter discusses the principle, kinetic and transport mechanisms,
stability of supported liquid membrane (SLM) design followed by thier configuration. In the …

One of the key steps in printed circuit board (PCB) production is etching of a thin copper
layer. Ammoniacal etching solutions are widely used for this purpose. Earlier we have …

Separation and recovery of copper from synthetic ammoniacal chloride solutions were
carried out systematically by solvent extraction using 1-phenyl-3-heptyl-1, 3-propanedione …

The main goal of this work was to study the extraction of copper (II) ions from
ammonia/ammonium chloride solutions with hydrophobic pyridineketoximes. The effect of …

Detailed theoretical mechanism of facilitated Cu (II) transport from ammoniacal wastewater
through hollow fiber supported liquid membrane (HFSLM) system based on the “Big …

Abstract Mg 2+ and PO 4 3+ were added into the synthetic wastewater, leading to the
dissociation of the complex ions in the wastewater, and resulting in removal of copper and …

The model of metal ion permeation through a bulk liquid membrane (BLM), based on the
Nernst–Planck equation, was developed. It was satisfactorily tested using the experimental …

Electroplating and other metal finishing industries, like every metal and metallurgical
industry, are associated with the generation of waste. Spent electroplating baths, waste …
