This paper makes a core-shell bismuth sulfide and graphitic carbon nitride composite by sonochemistry and uses it as an electrode to detect the antibiotic chloramphenicol, with recovery tests in milk and meat products. Bismuth sulfide is the electrode material; the analyte is the antibiotic.
Key numbers
This paper reports no numerical findings relevant to bismuth exposure.
Methods (brief)
The composite was synthesized with an ultrasonic horn and characterized; the sensor responded over 0.02 to 374.4 µM with a reported detection limit of 1.2 nM for the antibiotic (abstract).
Evidence fitness
This is a materials or analytical chemistry paper in which bismuth is a component of an engineered material. It does not support dietary exposure or toxicity claims for bismuth, and no bismuth was measured in food, water, feed, soil or human or animal tissue.
Limitations
Antibiotic results are outside the scope of this page.
