Optimization of fluorescence humification index calculation for low-concentration dissolved organic matter solutions.

The fluorescence normalized humification index (HIXn), defined as the ratio of the fluorescence intensity in the 435-480 nm region (I300-345) to the sum of the intensities in the 300-345 and 435-480 nm regions (I435-480) at an excitation wavelength o…
