Laser-induced fluorescence spectral data of humic acid solution in different noise patterns

The dataset contains laser-induced fluorescence spectral data in different noise modes. We used sodium humate and glucose according to the prepared solutions.

First, we prepared 100 mg per liter of f sodium humate solution A and glucose solution B. Depending on the molecular weight, solution A was prepared using 100 ml of water and 0.0149 g of sodium humate. solution B was prepared using 100 ml of water and 0.01584 g of glucose.

Subsequently, solution A and solution B were mixed in a ratio of 1:29 to obtain 100 mg per liter of sodium humate and glucose solution C.

Finally, solution C was diluted to obtain solutions of different concentrations for measurement.

We measured the COD of solution using a laser-induced fluorescence spectrometer, in which a 405 nm semiconductor laser was used as the excitation source for the spectrometer. The excited light signals from the test water sample pass through a filter, spectroscopic system and be focused into the CCD by a lens.
