Embodiment 1

[0043] A kind of sodium humate detection method, this method comprises the following steps:

[0044] Step 1: Determination of humic acid content

[0045] a1. Weigh 10 g of the sample, put it into a mortar and grind it, pass through a 100-mesh sieve, put 0.2 g of the sieved sample into the first 250 mL beaker, and add 70 mL of distilled water to the first beaker;

[0046] a2. Place the first beaker in a boiling water bath for extraction for 30 minutes. After the extraction is completed, take out the first beaker and place it on the test bench. After cooling to room temperature, transfer the extract in the first beaker to a 100mL volumetric flask. Accurately measure 5mL of distilled water into the first beaker with a pipette gun, wash the first beaker, and repeatedly wash the first beaker three times, transfer the washing liquid into the volumetric flask, and then use distilled water to make the volume of the liquid in the volumetric flask to the scale line;

[0047] a3. Filter...

Embodiment 2

[0063] Such as Figure 1 to Figure 4 A sodium humate detection device shown includes a sample preparation mechanism 1 and a heating and cooling mechanism 2 fixedly connected from front to back, and a titration mechanism 3 is fixedly installed on the right side of the heating and cooling mechanism 2;

[0064] The sample preparation mechanism 1 includes a storage box 11 and a support base 12 fixedly installed on the top surface of the storage box 11;

[0065] The left end of the top surface of the support base plate 12 is fixedly installed with two relatively symmetrical first connecting rods 121, and a weighing device 122 is arranged between the two first connecting rods 121, and the weighing device 122 is placed on the top surface of the supporting base plate 12. A second connecting rod 123 is installed vertically on the end of the connecting rod 121 away from the support base plate 12, and a mortar 124 is installed on the right side of the second connecting rod 123 to rotate,...

Abstract

The invention discloses a sodium humate detection method. The method comprises the following steps: step 1, determining the content of humic acid; 2, designing a blank experiment; and 3, calculating the total amount of sodium humate. The invention discloses the sodium humate detection method and sodium humate detection equipment, through the design of the sodium humate detection method, complete detection steps are provided for detection of the sodium humate in a biological sample; through the arrangement of the sodium humate detection equipment, the smooth implementation of the sodium humatedetection method is facilitated, and the operation of workers is facilitated.

Description

technical field [0001] The invention belongs to the technical field of detection, and in particular relates to a sodium humate detection method and equipment. Background technique [0002] Sodium humate is a macromolecular organic weak acid sodium salt with multiple functions, which is made of weathered coal, peat and lignite as raw materials through special processing. Its structure is relatively complicated. It is known that humic acid molecules contain benzene rings, Fused rings and some heterocyclic rings (such as pyrrole, furan, indole, etc.), there are bridges between the aromatic rings, and there are various functional groups on the aromatic rings, mainly carboxyl, phenolic, hydroxyl, methoxy , quinone group, etc. In the prior art, there are few complete and systematic methods for detecting the content of sodium humate, and there is no specific device for detecting the content of sodium humate. Contents of the invention [0003] The purpose of the present inventio...
