Description générale

Humic acid possess excellent complexing ability with heavy metal. Humic acid sodium salt acts as a proxy for humic-like substances that were identified as a major component of the isolated organic matter in the atmospheric aerosol.

Humic acid sodium salt, also known as sodium humate is used to synthesize superabsorbents.

Application

Humic acid sodium salt is suitable reagent used to study the hygroscopic growth of solid aerosol particles consisting of mixtures of ammonium sulfate, adipic acid and humic acid mixtures. It is suitable reagent used to study the phase transitions and hygroscopic growth of humic acid aerosols by Fourier transform infra-red (FTIR) spectroscopy and tandem differential mobility analysis (TDMA).
