A silica sol-based colorimetric sensor for Cd2+ detection in water was developed. The paper reports method development and characterisation; no food matrix samples are reported. Detection is for total Cd2+ in aqueous solution.
Key numbers
- LOD, linear range, and selectivity data in full paper.
Methods (brief)
Silica sol colorimetric detection of Cd2+. Water matrix only. Total Cd measurement.
Implications
Certification: Method development only; no food data. Courses: Demonstrates silica sol-based colorimetric sensing platforms.
