| dc.description.abstract | Accumulation of heavy metal in the environment becomes a health hazard because of their persistence, bioaccumulation and toxicity to plants, animals and human beings. Paper is increasingly accredited as a user-friendly and prevalent substrate for construction of microfluidic devices. Microfluidic paper-based analytical devices (μPADs) provide a substitute technology for development of economical, movable, disposable and low-cost diagnostic tools for improving point of care tests (POCTs). Hence, this microfluidic paper-based analytical devices (μpads) for rapid detection of iron metal in agricultural soil has reported LOD and LOQ as low as 5 ppm and 15 ppm for μpads analysis and 0.2 ppm and 0.6 ppm for UV/Visible spectroscopy. Calibration curve with linear range of 0.5 to 8 ppm for μpad and UV/Visible spectroscopy obtained 𝑅2=0.9248 and 𝑅2=0.9998 respectively. The fabrication of μpad using the paraffin wax on the qualitative filter paper was less than 10 minutes. The detection of iron in agricultural soil samples produced orange-red complex colour with the application of chromogenic reagent, 1, 10-phenanthroline. The advantages offered by this μPAD technique proposed herein in association with the improvements and low cost for iron detections for rapid, simple sample pretreatment and on-site measurement. | en_US |
