A pencil graphite-based disposable device for electrochemical monitoring of sulfanilamide in honey and water samples

Abstract

The present paper reports on the simple, fast, and inexpensive process of manufacturing a disposable pencil graphite electrode (PGE) from widely available materials, which showed reproducibility of at least 7.5%....

Sulfanilamide Electrochemical Sensor Using Phenolic Substrates and CO2 Laser Pyrolysis

“…Due to its widespread use, high SFD concentrations are released daily into wastewater from improper disposal of formulations containing SFD and from human urine and feces, as SFD, like many antibiotics, is only partially metabolized by most animals . SFD has poor biodegradability in nature, and it is now considered an emerging environmental pollutant, with its levels already explored in different samples, such as breast milk, honey, and water. , Intensive use of SFD is a public health concern owing to the health problems associated with exposure to high levels of it . Hence, affordable alternatives for SFD detection could help to quickly identify areas of high concentration, helping authorities manage exposure risk at the population level.…”
