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

What is the chemical formula of the humic acid salt? is it C9H8O4Na2? If not, what is the percentage of carbon in the humic acid salt?
1 Antwort-
Humic acid is a natural source material and exists in nature primarily as the sodium form. This is a technical grade product and in-depth analysis has not been performed, including carbon content. It is composed of a polycyclic core (mostly aromatic), loosely bound polysaccharides, proteins, phenols and chelated metal ions. The molecular weight can range from 2kDa - 500kDa, with the bulk being 20kDa - 50kDa. PubChem lists the formula as C9H8NA2O4. This would be the core formula.
Please refer to the link below for additional information from PubChem, including 2D and 3D core structures:
