A simple ligandless microextraction method based on ionic liquid for the determination of trace cadmium in water and biological samples

A Strategy Based on the Dispersive Liquid-Liquid Microextraction of Cadmium in Environmental Samples Prior to Its Determination by Flame Atomic Absorption Spectrometry

“…Our environment is becoming ever more polluted by heavy metals due to advances in industry, rapid population growth, and urbanization. This leads to land, water, andsoil pollution, which in turn is negatively impacting living organisms (1). Within this context, identifying heavy metals in environmental samples has become one of the most important subject areas within analytical chemistry.…”

“…11 Among these methods, DLLME has many advantages such as a short extraction time and low solvent use. [12][13][14] DLLME involves the formation of a cloudy emulsion of an organic solvent in an aqueous sample. This allows lead to partition into the organic phase when complexed with a suitable chelating agent.…”
