AI Technical Summary
Existing heavy metal detection technologies suffer from problems such as complex pretreatment, insufficient real-time performance, and high cost. In particular, portable detectors are expensive and cannot meet the needs of on-site or emergency monitoring.
Design a nonwoven fabric for heavy metal detection, including a substrate layer and a detection color development layer. The substrate layer is a cellulose-based nonwoven fabric, and the detection color development layer can react with metal ions to produce a colorimetric reaction. It is equipped with a colorimetric card, and a closed structure is formed by setting adhesive strips and transparent films around the detection area, which makes it easy to carry and operate.
It achieves heavy metal detection with simple structure, low cost, convenient operation and strong practicality, is suitable for field use and avoids sample diffusion and contamination.
