AI Technical Summary

Technical Problem

The prior art has problems such as expensive equipment, cumbersome operation and high requirements for instrument accuracy in zinc ion detection, making it difficult to realize low-cost and highly selective detection methods.

Method used

Deoxycholic acid is used as raw material, combined with microwave radiation technology to synthesize cholesteric molecular clamp artificial receptor D5, and identify and study through ultraviolet absorption spectroscopy and fluorescence spectroscopy to establish a method for rapid detection of zinc ions.

Benefits of technology

High selective identification and quantitative detection of zinc ions are achieved, with a detection limit of 0.78 μmol/L, which is lower than the maximum allowable concentration of zinc ions in drinking water by the World Health Organization and has anti-interference.
