Problems solved by technology

Polluted soil will lead to crop yield reduction, and even cause excessive pollutants in agricultural products, endangering human health
[0003] But the main way of pollution is often caused by a large amount of insecticides and fertilizers used in the process of planting crops. Insecticides and fertilizers usually contain more copper ions, so that a large amount of copper remains in the cultivated soil element, too much copper in the soil will not only cause soil pollution, but also affect the copper content of crops grown on the soil

Abstract

The invention discloses a copper ion contaminated acidic soil remediation agent and a preparation method thereof. The copper ion contaminated acidic soil remediation agent comprises the following groups by weight: 40-50 parts of fly ash, 5-10 parts of sodium aluminosilicate, 5-8 parts of montmorillonite, 3-6 parts of sodium alginate, 2-4 parts of PSAF, 1-3 parts of magnesium carbonate, 1-2 parts of zirconium sulfate, 1-2 parts of ferric sodium aluminate, 0.5-1 part of caustic sludge and 0.5-0.8 part of sodium humate. The invention also provides the preparation method of the copper ion contaminated acidic soil remediation agent.

Description

technical field [0001] The invention belongs to the field of soil remediation agents, in particular to a copper ion polluted acidic soil remediation agent and a preparation method thereof. Background technique [0002] There are many reasons for soil pollution, such as industrial sludge, agricultural garbage, sewage irrigation, pollutant deposition in the atmosphere, and the extensive use of mineral fertilizers and pesticides containing heavy metals. Polluted soil will lead to crop yield reduction, and even lead to excessive pollutants in agricultural products, endangering human health. [0003] But the main way of pollution is often caused by a large amount of insecticides and fertilizers used in the process of planting crops. Insecticides and fertilizers usually contain more copper ions, so that a large amount of copper remains in the cultivated soil Elements, too much copper in the soil will not only cause soil pollution, but also affect the copper content of crops gro...
