The invention provides a soil heavy metal passivation agent for remediation of soil contaminated by heavy metals and losing agricultural, industrial and commercial uses and the like. The method includes 1, contaminated soil mining; 2, medicament mixing; 3, soil backfilling; and 4, reuse of the ...
strong adaptability, high accumulation, easy growth and economic benefit will be selected and cultivated; soil heavy metal will be absorbed and enriched by macro fungi; multi-remediation technologies will be applied together; molecular biotechnology and genetic engineering technology will be integrated; an...
the remediation and treatment of heavy metal-contaminated soils should consider both the economy and effectiveness of the remediation technology. Microbial remediation is a typical remediation technology that will become the main development trend due to its effectiveness and low cost...
This paper reviewed the current situation and characteristics of soil contamination by heavy metal and remediation methods for soil heavy metal contamination applied in recent years are summed up and classified into six types according to mode of remediation in this paper,that is,engineering practice,...
Remediation methods of heavy metal contaminated soils from environmental and geotechnical standpoints 2023, Science of the Total Environment Show abstract Remediation of arsenic-spiked soil by biochar-loaded nanoscale zero-valent iron: Performance, mechanism, and microbial response 2022, Journal of Cleaner...
high efficiency and without secondary pollution. To some extent, it could bring economic benefit and ecological benefit. Combined with other methods, microbial remediation and phytoremediation technologies could improve the efficiency of soil heavy metal pollution remediation. On this basis, the emphasis ...
The agricultural industry is constantly facing soil pollution by heavy metals due to a wide range of chemicals present in various agricultural processes, such as pesticides, insecticides, weed killers, and fertilizers. Out of all the soil treatment methods, adsorption has more advantages. Numerous ...
The electro-remediation method of soil contaminated by heavy metal was researched by means of experiment in this paper, and the characteristic and mechanism for distribution and migration of heavy metal under an electric field were analyzed too. The experimental results indicated that the concentrations...
Concentration of heavy metals in soils and plants is given in Table 1. Sl.No Heavy metal Hithosphere Soil range Plants 1 Cadmium (Cd) 0.2 0.01-0.7 0.2-0.8 2 Cobalt (Co) 40 1-40 0.05-0.5 3 Chromium (Cr) 200 5-3000 0.2-1.0 4 Copper (Cu) 70 2-100 4-15 5 Iron (Fe) 50,...
These remediation techniques focus on reducing the maximum or bioavailable concentration of heavy metal in the soil11,12. Although these methods have high performance, most of them are expensive, harmful to the environment and time-consuming13,14. These traditional methods to remediate polluted soil ...
