In chemistry, pharmaceuticals, or soil science, leachate is generated by the process of “leaching.” It is an extraction technique for soluble products using a solvent, especially water. Leachate refers to the residual liquid resulting from the percolation of water through a material, particularly the soluble fraction.
Leachate analysis: what is it for?
Leachate analysis is mainly used for environmental purposes; for example, when water flows through soil or a substrate containing toxic substances (an industrial landfill or household waste).
Leachate analysis also makes it possible to highlight the presence (or absence) of pollutants such as heavy metals, plasticizers, fatty acids, mineral compounds, microorganisms… Indeed, because of their significant pollutant load, leachates can be the source of contamination in groundwater, surface water, or even soil.
Certain European regulations, such as the landfill and waste directives, require leachate treatment. These regulations are intended to prevent and reduce their harmful effects on health and the environment.
The FILAB laboratory supports you with your leachate chemical composition analysis needs
Dans un contexte environnemental, vous cherchez à démontrer la présence ou l’absence de polluants toxiques avec le support d’un laboratoire compétent. FILAB met à votre disposition son parc analytique pour vous accompagner dans ce besoin :
- Etude de la composition chimique d’un lixiviat par ICP-AES ou ICP-MS
- Préparation d’un lixiviat par la technique de lixiviation sur un matériau ou une poudre
