  • Robust carbon dots (CD) as an artificial tracer for groundwater studies
    Patent number: 11725509
    Abstract: The disclosure provides methods for the measurement of ground water characteristics. The carbon dot tracer is injected in an injection bore well. Carbon dot tracer and ground water are thoroughly mixed in the injection bore well. The ground water mixed with carbon dot tracer is pumped from the injection bore well to an acquiring bore well connected with injection bore well with micro and major fracture; the water samples mixed with carbon dot tracer were collected at the acquiring bore well. The characteristics of the ground water were measured by measuring fluorescence. The disclosure further relates to a method for depicting the solute transportation in the soil.
