Recent trends of copper detection in water samples

Abstract

Abstract Background Water pollution due to the disposal of heavy metals in water bodies is one of the most global concerns that adversely affect the ecosystem and human health because of their non-biodegradability and potential of accumulation. Copper is one of the most present metals in the environment released mainly from disposing of agricultural fertilizers and pesticides, mining operations, chemical, pharmaceutical, and paper manufacturing industries into stream bodies. The elevated exposure to Cu(II) causes severe toxicity, diabetes, anemia, kidney disorders, liver damage, and death. Main body Several researchers developed detection methods and techniques for Cu(II) detection in the different water samples and sources to ensure that Cu(II) concentration falls within the acceptable limit range, including atomic and molecular spectrophotometry, mass spectroscopy, sensors, voltammetry, and chromatography. This review spotlights recent Cu(II) detection trends in water samples, highlighting their detection limits, advantages, and disadvantages. Conclusion Based on the water sample, detection limit, method cost, an appropriate analysis can be used. Recent trends of Cu(II) detection in water samples include atomic and molecular spectrophotometry, mass spectroscopy, sensors, voltammetry, and chromatography. The principle, definitions, experimental work, advantages, and disadvantages of each method are discussed and highlighted.
