2024-09-08
BICINE buffer (chemical name N, N-dihydroxyethylglycine, CAS number 150-25-4) has significant application value in soil remediation, especially in heavy metal contaminated soil remediation. The following are the main reasons why BICINE buffer can be used for soil remediation:
BICINE powder
1. Excellent chelating performance
Molecular structural characteristics: BICINE molecules contain two hydroxyl groups (- OH) and one carboxyl group (- COOH), which endows them with excellent chelating properties.
Heavy metal chelation ability: BICINE can chelate heavy metal ions such as copper (Cu), cadmium (Cd), and lead (Pb) to form stable chelates. This chelation can desorb heavy metals from soil particles and dissolve them in solution, thereby reducing the toxicity of heavy metals in soil.
2. Selective chelation
Avoiding nutrient loss: It is worth noting that BICINE does not chelate essential plant nutrients such as calcium (Ca) and magnesium (Mg) in the soil while chelating heavy metal ions. This characteristic ensures that the soil can maintain its fertility during the remediation process, avoiding soil quality degradation caused by the remediation process.
3. Environmental friendliness
No secondary pollution: Traditional soil remediation methods, such as acid washing and heat treatment, often cause secondary pollution to the environment or damage soil structure. In contrast, BICINE, as a buffer and chelating agent, has higher environmental protection. The use of BICINE as an active component in the leaching solution can not only repair heavy metal contaminated soil, but also prevent the loss of plant nutrients such as calcium and magnesium in the soil, which is safe and environmentally friendly, and will not cause secondary pollution to the environment.
4. Improve repair efficiency
Bicine can improve remediation efficiency by adjusting soil pH and chelating heavy metals. It can promote the desorption of heavy metals from the surface of soil particles, making them easier to remove or transform into more stable forms.
5. Application examples
In practical applications, BICINE buffer has been widely used in the remediation of heavy metal contaminated soil and has achieved significant results. It has broad application prospects as a soil remediation agent and has received extensive attention in the field of environmental science. Although Bicine has shown remediation potential in laboratory and small-scale experiments, its application to large-scale soil remediation projects still needs to consider factors such as cost-effectiveness, long-term environmental impact, and synergistic effects with other remediation technologies. In addition, soil type, pollutant type and concentration, and other environmental conditions can also affect the remediation effect of Bicine.
Product packaging
In summary, BICINE, as a biological buffering agent, has become an important remediation material in the field of soil remediation due to its excellent chelating performance, selective chelation, environmental friendliness, wide applicability, and significant effects in practical applications. The BICINE buffer produced and developed by Desheng has received unanimous praise from customers for its small inter batch differences, high purity, low chloride ion content, and customizable production.
