Rapid, sensitive, and selective copper (II) determination using sensitive chromogenic azo dye based on sulfonamide

A Potentiometric Sensor for the Determination of Pb(II) Ions in Different Environmental Samples

“…However, PVC-based membranes are often preferred by researchers in the preparation of ISEs since PVC can easily hold the membrane mixture. [8] Lead is a toxic heavy metal commonly used in products such as acid batteries, cosmetics, cables, solders, paints, alloys, pigments, ammunitions, high quality glasses, and rust inhibitors. [9,10] Due to its common use, lead severely pollutes and harms the environment.…”

Synthesis of highly stable fluorescent poly(methacrylic acid-co-itaconic)-protected silver nanoclusters and sensitive detection of Cu2+

“…11 To date, elaborate efforts have been made to prepare water-soluble AgNCs by using different templates including DNA, thiolates and polypeptides. 4,12,13 For example, AgNCs synthesized from DNA template stabilizer can present signicantly enhanced uorescence, 14 and those from 2,3-dimercapto-succinic acid as a template stabilizer have an exact number of Ag atoms. 15 Recently, Cao N. et al reported the synthesis of glutathione-protected uorescence AgNCs by the boiling water method and applied for the detection of cysteine.…”

“…[19][20][21][22] As we all know, copper, as one of the most fundamental trace elements and a vital cofactor for many enzymes in the human body, plays an irreplaceable role in some physiological processes. 12,13,18 Abnormal copper content may cause negative effects on human health and even serious diseases, such as Alzheimer's disease, Parkinson's disease, and motor neuron disease. 12,23,24 Therefore, it is more and more important to establish copper detection methods in related chemical and biological samples.…”

“…12,13,18 Abnormal copper content may cause negative effects on human health and even serious diseases, such as Alzheimer's disease, Parkinson's disease, and motor neuron disease. 12,23,24 Therefore, it is more and more important to establish copper detection methods in related chemical and biological samples. Several techniques have been employed to detect Cu 2+ , such as dispersive liquid-liquid microextraction, liquid chromatography-mass spectrometry, UV-vis spectroscopy, and atomic absorption spectroscopy.…”
