Abstract
The present disclosure relates to a kit and method for testing harmful heavy metals onsite, which can determine the presence or absence of harmful heavy metals and the degree of contamination with harmful heavy metals dissolved in water or contained in sediment, soil, deep-sea mining tailings and the like. The kit includes a receiving member and a diagnostic solution containing a biosurfactant, which is accommodated in the receiving member and undergoes an ion exchange reaction with a liquid including harmful heavy metals or a solid sample from which harmful heavy metals are leached in a liquid phase.
Claims8
A recognition kit for recognizing a harmful heavy metal, comprising:
- a receiving member;
- a diagnostic solution containing at least one biosurfactant, which is accommodated in the receiving member and a color of which changes upon reaction with the harmful heavy metal.
A method of recognizing a harmful heavy metal, comprising:
- manufacturing a recognition kit including a receiving member and a diagnostic solution containing at least one biosurfactant;
- placing a sample in the receiving member of the recognition kit to allow the sample to react with the diagnostic solution;
- and
- recognizing presence or absence of the harmful heavy metal in the sample by visually observing a color change in the diagnostic solution.
