General description

Humic acid possess excellent complexing ability with heavy metal.[1] 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.[1]

Humic acid sodium salt, also known as sodium humate is used to synthesize superabsorbents.[2]

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.[1] 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).[3]
