This review article summarizes the opportunities for utilizing the green analytical chemistry (GAC) techniques and principles in the field of quality control (QC) of pharmaceuticals. Green analytical chemistry is considered a branch of the green chemistry based on the principles overlapping with the goals of sustainable development. General definitions of quality and quality control, the principles of GAC, proposals for greener sample pretreatment and greener chromatographic method of analysis applied in QC laboratories are discussed herein. The main goal is to achieve more eco-friendly analysis in QC laboratories through different strategies and techniques, replace toxic reagents, and modify or replace analytical methods and/or techniques with safer ones, making it possible to dramatically reduce the amounts of reagents consumed and waste generated. 相似文献

Green analytical chemistry is a comprehensive perspective that aims to reduce or eliminate the toxic and harmful solvents, reagents, and techniques in the preparation, pre-treatment, and determination steps of an analysis process. With the increase in environmental pollution in recent years, awareness has been increasing in terms of both the contamination analysis of environmental sources and the more environmentally friendly analysis methods. This review evaluates the solvents such as bio-based solvents and deep eutectic solvents, nanomaterials synthesized by non-toxic methods, the greener changes in the extraction methods, and chromatographic techniques considering the most recent studies. In particular, trying to make the methods used to analyze environmental samples safer and less toxic is an important point that overlaps with the green approach, which aims to minimize environmental pollution. In this context, this review provides information on green analytical chemistry-based environmental applications covering the last ten years so that the applications of this approach can be examined and understood in more detail and can be applied by other researchers. 相似文献

The principles of green chemistry are applied to not only chemical engineering and synthesis, but also increasingly analytical chemistry. We describe environment-friendly analytical techniques applied to isolate and to enrich trace organic pollutants from solid and aqueous samples. Amounts of organic solvents used in analytical laboratories are reduced by applying solventless extraction, extraction using other types of solvent, assisted solvent extraction and miniaturized analytical systems. 相似文献

The basic concepts of traceability as they are defined by the Comité Consultatif pour la Cluantité de Matière are contrasted
with the practical exploitation in chemical analysis. The applicability of traceability concepts are tested for their practical
applicability on four different analytical methodologies, neutron activation analysis, plasma mass spectrometry, beam microscopical
analysis and speciation analysis of organometallic compounds.

Long-chain alkylbenzenes: their analytical chemistry, environmental occurrence and fate 总被引:1,自引:0,他引:1

Since ca. 1950 long-chain alkylbenzenes have been produced industrially for the synthesis of alkylbenzenesulfonates, the anionic surfactants most commonly used in commercial detergents. Prior to 1965 the alkylbenzenes were generated by Frieldel-Crafts alkylation of benzene with tetrapropylene. This reaction produces a complex assemblage of phenylalkanes (TABs) having highly branched side chains. Due to their stability, the TABs proved to be environmentally troublesome and were ultimately replaced (during the mid-1960s) by the linear alkylbenzenes (LABs). The LABs consist of a mixture of secondary phenylalkanes with linear alkyl side chains ranging in length from C10 to C14. Because of their unique structures and composition, these compounds are easily identified and measured in complex environmental samples. The linear alkylbenzenes are also found in municipal wastewaters where their presence is thought to result from the use of domestic and industrial detergents. Because they are synthetic and unlikely to occur in other significant inputs to coastal marine waters, long-chain alkylbenzenes have obvious potential as waste-specific molecular tracers. The presence of long-chain alkylbenzenes in sediment trap particulates and marine sediments collected near a major waste outfall system in southern California indicates that these hydrocarbons can survive exposure to an oxygenated water column during sedimentation. Whereas changes in the isomer composition of the LABs with depth in the sediments are suggestive of microbial alteration, the vertical distribution of the TABs and LABs can be used as a geochronological tool to reconstruct waste depositional histories. 相似文献
