Humic acid­­(singular) the acid radical found in humic matter which is soluble in alkali but insoluble in acid, methyl ethyl ketone, and methyl alcohol. Humate­­the salts of humic acids, collectively, or the salts of humic acid specifically.

of this study was to investigate the extraction of humic acid from three lignite coals from different locations of the country. The effect of KOH concentration on extraction of humic acid has been investigated and the extracted humic acids were evaluated using standard gravimetric method,

indigenous raw material in the form of lignitic coal and indigenous production technology; Recently in 2014 India imported humic acid worth USD 3,404,733 with total quantity of 4,929,168. China is the largest supplier of humic acid accounting for imports worth USD 3,134,406 followed by United States and Canada which exported humic acid worth USD 133,216 and USD 67,057 respectively.

The results show that the optimum conditions of dry process are concentration of nitric acid of 40%, reaction temperature of 95°C, reaction time of 5 min. The optimum conditions of wet process production are concentrations of nitric acid of 20 % ~ 25%, the solidliquid ratio of 1: (weight ratio), reaction temperature of 80 ~ 85°C, and reaction time of 30 min.

Besides fulvic acids and humins, humic acids belong to the humic substances and form the biological centre as the main fraction. Humic substances are formed during the chemical and biological humification of plant and animal materials. The humic acidcontaining sedimentation layers of soft lignite are usually close to the surface and are called Leonardites.

The process of lignite formation depends on many conditions, including the development of ... Humic substances in lignite Humic and fulvic acids are the final breakdown constituent in the natural ... hormones production is higher, roots system is well developed and permeability of .

Coal humic acid is a fraction of coal humic substances prepared by the partial oxidation of coal and has a number of properties that make it attractive as a material to treat pollutants in water, stack gas, and other pollutant sources.

Nitro humic acid was extracted from lignite of Guizhou Anshun, which production condition and process were studied. The results show that the optimum conditions of dry process are concentration of nitric acid of 40%, reaction temperature of 95°C, reaction time of 5 min. The optimum conditions of wet process production are concentrations of nitric acid of 20% ~ 25%, the solidliquid ratio of 1 ...

Jul 14, 2015· Leonardite ranges considerably in humic and fulvic acid content. For example, deposits can have as low as 10% humic acid content and as high as 78%. It's derived from Lignite based coal and was formed in salt water deposits. The other 2090% of the product that isn't the active ingredient is made up of ash and heavy metals.

Extraction liquid used in isolation process of humic acids from lignite should be characterized by high efficiency and selectivity of extraction and neutral influence on the physicochemical properties of the obtained compounds.

Mar 20, 2014· Fulvic acidthe acid radical found in humic matter which is soluble in alkali, acid, methyl ethyl ketone, and methyl alcohol. Fulvates the salts of fulvic acid. Leonardite a soft brown coallike deposit usually found in conjunction with deposits of lignite.

Leonardite based coal is soluble in the alkaline conditions because of the high content of humic acid. Humic acid is obtained from Leonardite by extraction with sodium or potassium hydroxide followed by coagulation, centrifugation and washing with water. Multivalent metal humates were produced from water soluble sodium or potassium humates and metal salts. The production of metal humates from .

The effects of lignite humic acid and inorganic fertilizer additions on the productivity of typic haplustalf in Tamil Nadu, India M. SANGEETHA AND P. SINGARAM The Asian Journal of Soil Science (2007 ) 2 (1 ) : 8689 Key words: Bulb yield, Cation exchange capacity, Lignite humic acid, Onion. Soil health is one of the key factors, which decides the

Task – Extraction of Humic Acid from L owash Lignite: The goal is to extract high purity HA from the low ash lignite generated in Task 2 for anode preparation in Task 4, collect the low ash humins for char production in Task 5, along with the recovery of fulvic acid as a high value by .

From hydrophilic fractions of lignite and humic acids, malonic acid and succinic acid are dominant Lignite compounds and could indicate that methylene and ethylene chains are main bridge bonds connecting Malonic acid between the aromatic rings in the structure.

I've written before about Fulvic Acid and how I take fulvic and humic did you know that Humic Acid is the byproduct of an 80 million year old, ongoing process of humification? It is a natural geological process (like photosynthesis) which creates a byproduct known as humates (which humic acid is derived from).

reviews their use in agriculture and points to consider before using humic materials. Carboxyl Phenolic group group Figure 1. A simplified example of the structure of humic acid extracted from soil. Humic materialial can be extracted from soft brown coallike deposits called leonardite, found with lignite coal.
