Green sample preparation strategies for organic/inorganic compounds in environmental samples

Abstract

Green sample preparation strategies for organic/inorganic compounds in environmental samples, Current Opinion in Green and Sustainable Chemistry,

Recent progresses in analytical method development for 210Pb in environmental and biological samples

“…Considering the impact on the environment and the concept of sustainable development, in the process of chemical analysis, sample preparation is considered to be the main source of pollution (Cerutti et al 2019 ; Lopez-Lorente et al 2022 ). The concept of green sample preparation and green analytical chemistry is the main trend of analysis today.…”

Green sample preparation methods in the environmental monitoring of aquatic organic pollutants

“…In addition, there has been an ongoing focus on the development of alternative solvents which are biodegradable and less toxic than conventional solvents which are also highly volatile and flammable [9]. A comprehensive review of the history and development of green extraction techniques in green analytical chemistry was published in 2019 [10] as well as a review on green sample preparation strategies for environmental samples [11], which covered both inorganic and organic analytes. In this section recent progress in this field focusing on organic pollutants in water is reviewed.…”

Simultaneous determination of Cd, Pb, Cu and Zn as total and labile fractions in soil using a small-sized electrothermal vaporization capacitively coupled plasma microtorch optical emission spectrometer after diffusive gradients in thin-film passive accumulation

“…3 To achieve the required sensitivity, these spectrometric techniques are oen coupled with preconcentration/accumulation procedures by solid phase extraction, liquid-liquid extraction, direct liquid or solid micro-sampling by electrothermal vaporization (ETV) and laser ablation (LA), or derivatization by generating chemical vapor using the classical method or the UV photoinduced procedure. [4][5][6][7][8][9][10][11][12][13][14][15] Although the ICP-OES and ICP-MS techniques are high-performing and provide excellent sensitivity, the laboratory-scale equipment involves high operating costs related to energy consumption and Ar as a support gas for plasma generation and is still not easily accessible for many laboratories. On the other hand, line-source atomic absorption is by its very nature a sequential, slow method with high sample consumption and less competitive with the simultaneous methods in the current state of the art.…”
