Abstract
The present invention discloses a new method for extracting humate from efflorescent coal. In the method, the efflorescent coal as a raw material is pulverized and added into a reaction kettle, water and alkali metal silicate are added, heated at the temperature of 40DEG C to 80DEG C, stirred to react for 0.5 to 1 hour and then shifted into a settling tank, and extracting liquid is filtered. The method has the advantages of high extraction rate, low cost, no pollution and improvement in the prior art. The humate solution is directly prepared into a liquid fertilizer taken from the nature and used for the nature, and the liquid fertilizer having the functions of a humic acid fertilizer and performing the action of a silicon fertilizer nicely promotes the development of green agriculture.
Description
Technical field
The present invention relates to a kind of method of extracting humate, relate in particular to a kind of method of extracting humate with alkalimetal silicate.
Background technology
Humic acids is a kind of natural organic high molecular compound, be present in peat, careless carbon, ocean, soil and the grizzle material, contain groups such as elements such as carbon, hydrogen, oxygen, nitrogen and aromatic proton, phenolic hydroxyl group, carboxyl, methoxyl group, have performances such as slightly acidic, wetting ability, ion exchangeable, oxidation-reduction quality and physiologically active.Humic acids is extracted from weathered coal, make agricultural fertilizer or as plant-growth regulator, be used widely in China with the form of humate, this class fertilizer is fertile to improving the soil, protecting, good effect has all been played in volume increase.
The production method of existing the most frequently used humate be with: low calcium and magnesium peat or weathered coal add the caustic soda soln of 1%-2% after crushed, heating is behind sedimentation and filtration, reheat is inspissated, through stack gas oven dry exhaust, get rotten sodium (potassium) solid after the pulverizing, perhaps directly after crushed, be put in the pond, add directly to macerate behind the alkali mixing and get with the peat composed of rotten mosses or weathered coal.This method working substance extracts insufficient, and product ash content height is unfavorable for the absorption of plant, and the humic acids free settling.The development and application of current humic acid fertilizer is particularly urgent for the development green agriculture, and as the humate of humic acid fertilizer major ingredient, its leaching process is improved, reduces its cost, improves its extraction yield, will help the development of humic acid fertilizer.For this reason, improve the extractive technique of humate, fully improving its extraction yield has very important meaning.
Summary of the invention
Purpose of the present invention is the humic acids extracting method is improved, and provides a kind of and can not only improve not free settling of its extraction yield, humic acids, but also contain the humate new method for extracting of siliceous fertilizer effective ingredient.
In order to realize the object of the invention, this invention technical scheme is as follows:
With alkalimetal silicate under 40 ℃ of-80 ℃ of conditions, directly humic acids is extracted from weathered coal, alkalimetal silicate with the ratio of the weight of weathered coal is: 1: 0.1～1, concrete steps are as follows: 1. weathered coal is pulverized, add in the reactor, add entry, alkalimetal silicate, the heated and stirred reaction is 0.5-1 hour under 40 ℃ of-80 ℃ of conditions, change in the settling bath, filter extracting solution; 2. be that the direct can of humate becomes serial liquid fertilizer with extracting solution.During use foliage-spray is carried out in its dilution, its effective concentration is 400～1000ppm.Described alkalimetal silicate is water glass, Starso.
This method selects for use alkalimetal silicate to substitute caustic soda, has stronger alkalescence based on its aqueous solution of alkalimetal silicate, its pH value is generally between 12.5～13, and it has surge capability preferably, the silicic acid that can make generation is free settling not, contain siliceous fertilizer effective constituent again simultaneously thereby make this extracting solution not only contain humate, directly made foliage-spray composite fertilizer, cost is lower and raw material availability is higher.
Beneficial effect of the present invention is as follows:
1) chooses alkalimetal silicate and replace caustic soda sodium hydroxide, reduced the solution pH value, it is remained between the 7-8, can make all free settlings not of silicic acid in the solution, humic acids, help directly humate solution being mixed with liquid and spray fertilizer; The liquid fertilizer that this is mixed with, acidity is low, help improving soil quality, optimize Soil structure, and this fertilizer contains sio
3 2-Ion, make its advantage that has siliceous fertilizer concurrently again, through evidence, humate combines with siliceous fertilizer, the light and the cooperation that not only can improve crop used, the ability of the disease and insect resistance of enhancing crop also can strengthen the drought-resistant ability of crop, also activate the phosphorus in the soil, improves the utilization ratio of phosphate fertilizer.The at present domestic product that does not also have humate and siliceous fertilizer to make fertilizer for spraying on leaf surface occurs; 2) this method has improved the extraction yield of humic acids in the weathered coal, and extraction yield is 65%～75%.
