Embodiment 1

[0046] Step 1. Mix the substrate evenly according to the ratio of peat: vermiculite: perlite volume ratio 3:1:1.

[0047] Step two,

[0048] Control (CK): Weigh 2.1kg of evenly mixed matrix, measure 50mL of 0.375mM cadmium chloride (CdCl 2 2.5H 2 0) Add 1.95L of distilled water and stir evenly, add the mixed solution into the matrix and stir evenly, evenly pack the mixed matrix into 15 nutritional bowls with a diameter of 10cm×high 9cm and cover with a film for subsequent use;

[0049] T 50 : Weigh 2.1kg of uniformly mixed matrix, measure 50mL 0.375mM CdCl 2 2.5H 2 O was added to 1.85L distilled water and stirred evenly, and the mixed solution was added to the matrix and stirred evenly, and 50mL of 2% (mass percentage) CaCl was first added to the matrix. 2 The solution is stirred evenly, and then 50 mL of 1% (mass percentage) NaAlg solution is added to the matrix and stirred evenly, and the mixed matrix is ​​evenly packed into 15 nutritional bowls with a diameter of 10 cm...

Abstract

The invention relates to the application of sodium alginate and calcium chloride in the preparation of cadmium embedding agent, the cadmium embedding agent, the method and application of cadmium embedding, and belongs to the technical field of cadmium pollution control. The invention provides the application of sodium alginate and calcium chloride in preparing cadmium embedding agent. The cadmium embedding agent prepared by the application of the present invention can reduce the cadmium absorption of crops planted in cadmium-polluted soil or matrix.

Description

technical field [0001] The invention relates to the technical field of cadmium pollution control, in particular to the application of sodium alginate and calcium chloride in preparing a cadmium embedding agent, the cadmium embedding agent, and the cadmium embedding method and application. Background technique [0002] With the rapid development of industry and agriculture, the problem of soil environmental pollution is becoming more and more serious. Among all heavy metal pollution, cadmium pollution is the most serious. Cadmium is a heavy metal that can have a huge toxic effect on organisms, reduce the yield and quality of crops, and enter the human body through the enrichment of the food chain to endanger human health. The control of soil cadmium pollution has attracted extensive attention at home and abroad. [0003] At present, the remediation technologies for soil containing heavy metals mainly include physical, chemical, electrokinetic, biological and agricultural ec...
