Heat is used to increase the solubility of humic acids and hence more potassium humate can be extracted. The resulting liquid is dried to produce the amorphous crystalline like product which can then be added as a granule to fertilizer. The potassium humate granules by way of chemical extraction lose their hydrophobic properties and are now ...
It is an oxidation product of lignite, associated with near-surface mining. [1] It is a rich source of humic acid (up to 90%) [2] and is used as a soil conditioner, as a stabilizer for ion-exchange resins in water treatment, [3] in the remediation of polluted environments and as a drilling additive. [4]
Extracted humic acid not a single acid; rather, it is a complex mixture of many different acids containing carboxyl and phenolate groups so that the mixture behaves functionally as a dibasic acid or, occasionally, as a tribasic acid. Commercial humic acid used to amend soil is manufactured using these same well established procedures.
It is reducible to a fine powder by trituration, and if submitted to the action of a weak solution of potash, it yields a considerable quantity of humic acid. [39] Leonardite is an oxidized form of lignite, which also contains high levels of humic acid. [58] Jet is a hardened, gem-like form of lignite used in various types of jewelry. [42]
The food-grade product meets the requirements set out in the Food Chemicals Codex. It is denoted by E number E514ii in the EU and is approved for use in Australia and New Zealand [36] where it is listed as additive 514. Food-grade sodium bisulfate is used in a variety of food products, including beverages, dressings, sauces, and fillings.
The Food Protection Committee started in 1961 to provide objective quality standards for food-grade chemicals. Parts of the first edition were published in loose-leaf form between 1963 and 1966. The scope of the first edition is limited to substances amenable to chemical characterization or biological standardization which are added directly to ...
Essential items include a few days’ supply of food and water, bowls, any necessary medications, a first aid kit, and comfort items like a blanket or a toy. Including a recent photo of the pet ...
The International Humic Substances Society maintains a collection of standard and reference samples of humic and fulvic acids extracted and fractionated from leonardite, river water, a mineral soil, and peat, plus natural organic matter isolated from river water by reverse osmosis, [4] without fractionation.
