Amorphous organic weak acid mixture. Note. Its main components are humic acid, fulvic acid and insoluble humin. 2.1.2 Humic acid A group of relatively large molecular weights of humic substances can only be dissolved in dilute alkali solution, not soluble in acid and water, and has aromatic and aliphatic groups. A mixture of amorphous organic acids of a black or brownish black color that is characteristic of a variety of functional groups. 2.1.3 Mineral source humic acid mineralhumicacid Humic acid extracted from organic minerals such as weathered coal, lignite, peat, and oil shale. 2.1.4 Biomass humic acid bio-humicacid; BHA Biological humic acid Non-mineral biomass by-products produced by industry and agriculture are humic acids obtained by biological or chemical process techniques. 2.1.5 Native humic acid protogenesishumicacid Humic acid formed by minerals such as peat and lignite during mineralization. 2.1.6 Regenerated humic acid, paingenesishumicacid Humic acid produced by the action of microorganisms and oxidation in weathered coal. 2.1.7 Free humic acid (alkaline acid precipitation) freehumicacidbyacidprecipitation The acidic functional group remains in a free state, i.e., an acidic group that binds to the active H ion. In the actual extraction process, 1% hydrogen hydroxide The humic acid obtained by extracting sodium from a mineral source humic acid raw material and precipitating with an acid having a pH of 1.0. 2.1.8 Combined humic acid combinedhumicacid A humic acid in which an acidic functional group is combined with a high-valent metal ion such as calcium magnesium. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 38073-2019_English be delivered?Answer: Upon your order, we will start to translate GB/T 38073-2019_English as soon as possible, and keep you informed of the progress.
