Potassium Humate and Fulvic Acid Analysis

by admin 0 Comments

Potassium humate and fulvic acid are particularly interesting because they both contain molecular structures of polar and non-polar substituents, so they can transport both water-soluble and water-insoluble species. Indeed, colloidal organics.

For example, soluble humic acid and fulvic acid found in groundwater and surface water are called “third stage” in the traditional two-stage. Solid and water phase systems are used for hydrochemical modeling. Because potassium humate and fulvic acid in the colloid size range are key factors in chemical waste migration and other hydrological processes
A process that can produce enough humus and yellow rot material like fulvic acid.

Sampling methods. Chemical and physical characteristics change with size are necessary for improvement. Our understanding of their role in hydrogeochemistry. Classic method for separating potassium humate and fulvic acid from soil and water. The pH is about 2.

Many studies have attempted to remove metals from humus and treated fulvic acid with hydrochloric acid and hydrogen fluoride. These methods are because strong chemical treatments will change the chemical structure of humus and fulvic acid through acid-catalyzed reactions (decarboxylation, degreasing, etc.) and cause physical changes in shape (hence effective diameter). Other methods to minimize.

Including radionuclides and toxic metals in their natural geochemical state) A method of sampling and sizing of potassium humatefulvic acid, and other humic acids.

Organic and inorganic colloidal materials from groundwater or surface water can be reproduced with minimal artifacts (chemical and physical artifacts). The method should be suitable for processing a large amount of water to obtain sufficient materials for multiple analytical procedures (infrared, C-NMR, pyrolysis, chromatography, mass spectrometry, etc.) Methods should also be relatively simple and easy to use, and easy to use in the laboratory, especially in outside

Potassium Humate to Remove Lead and Cadmium in Soil

by admin 0 Comments

Potassium Humate is also used for the rehabilitation of soil contaminated by heavy metals like lead and cadmium due to their unique physicochemical properties.

Soil heavy metal pollution is an important environmental problem facing China and many other countries in the world. The soil in situ fixation/stabilization technology is widely used in practical engineering due to its ease of operation, rapid repair, and low cost.

In this paper, the effect of potassium humate on single and composite pollution of lead and cadmium was studied by laboratory culture experiments, using heavy metal morphological extraction and bioavailability in vitro methods, and by assessing soil health risk based on bioavailability.

The main research results are as follows: (1) For lead-contaminated soil, the changes in the form of heavy metals with the addition of potassium humate are manifested as: the content of weakly acid-extracted and reducible lead decreases, and the content of oxidizable and residual lead increases. Two in vitro extraction methods (SBET and PBET) were used to determine the bioavailability of lead. The results showed that with the increase in the amount of potassium humate, the bioavailability of soil lead decreased significantly. Based on the consideration of land use types, health risk assessment is conducted. It can be seen that the hazard quotient of sensitive land is higher than that of non-sensitive land, and the risk control value of pollutants is lower than that of non-sensitive land. The calculation results obtained using the bioavailability-optimized health risk assessment model show that as the amount of potassium humate increases, the hazard quotient of the contaminated soil is significantly reduced, and the risk control value of a lead is significantly increased.
(2) For different concentrations of cadmium contaminated soil, the changing trend of heavy metal forms with the addition of potassium humate was mainly manifested by the conversion of weakly acidic cadmium to oxidizable and residual cadmium. The PBET method was selected as the in vitro extraction method of biodegradability. The results showed that the biodegradability of cadmium decreased with the increase of potassium humate, and increased with the increase of cadmium pollution

Potassium Humate Desulfurization of Flue Gas

by admin 0 Comments

Flue-gas desulfurization is the main method of coal desulfurization. Potassium humate (KHA) solution was used to remove SO2 from flue gas, and the effects of the potassium humate concentration, solution temperature, SO2 concentration, and oxygen content on SO2 absorption efficiency were explored.

The results showed that the desulfurization performance of potassium humate absorbent is much better than that of an equal volume of water or potassium hydroxide solution with the same initial pH. The SO2 concentration, reaction temperature, and oxygen content greatly influence HEDT (high-efficiency desulfurization time).

When the concentration of KHA is between 0.024–0.120 g/L, HEDT increases as the potassium humate concentration increases; after desulfurization, the potassium humate product is poorly soluble in water and is easy to separate. Implementation of the desulfurization process by potassium humate mainly involves providing alkalinity and pH buffering agents in the desulfurization process.

Do you really understand Potassium Humate?

Do you really understand Potassium Humate?
potassium-humate
With the advancement of agricultural technology, potassium humate has become a relatively common product in the market, so do you really understand potassium humate? Whether potassium Humate is organic fertilizer or chemical fertilizer is a common problem. Next, we will introduce you to the function of potassium humate as organic fertilizer or chemical fertilizer and potassium humate to help you better use potassium humate. Is Potassium Humate an organic fertilizer or a fertilizer? Potassium Humate is high-efficiency organic potash because humic acid is a biologically active preparation that increases soil available potassium content, reduces potassium loss and fixation, increases potassium uptake and utilization by crops, and improves the soil. To promote crop growth, improve crop resilience, improve crop quality, and protect the agricultural ecological environment; potassium humate can be mixed with urea, phosphate fertilizer, potassium fertilizer, trace elements, etc., and can be made into high-efficiency multi-functional compound fertilizer; Potassium humate can also be used as a treatment agent for petroleum drilling fluids, mainly to prevent the collapse of the good wall. Humic acid and its products have many uses. In agriculture, Humic Acid fertilizers (such as ammonium humic acid fertilizers can be made by neutralizing humic acid with ammonia) in combination with nitrogen, phosphorus, potassium and other elements, with fertilizers to enhance efficiency, improve soil, stimulate crop growth, improve the quality of agricultural products and other functions. Potassium Humate
  • Potassium humate improves soil aggregate structure and improves soil water retention and fertilizer retention capacity.
  • Potassium humate stimulates the root growth of crops and enhances crop root adhesion and nutrient uptake capacity.
  • Potassium humate shortens the maturity of the crop and allows the crop to mature for about ten days. Promote the increase of melon and fruit crops, and increase the yield by more than 10%.
  • Potassium humate prolongs the fresh-keeping period and picking period of fruits and vegetables prevents falling flowers and fruit drop, increases the sugar content of fruits, and improves fruit quality.
