Leaching is the process of extracting substances from a solid by dissolving them in a liquid, . The same analysis with citric acid showed similar results with an optimal temperature and concentration of 90 °C and 1.5 molar solution of citric acid.
Leaching is the loss or extraction of certain materials from a carrier into a liquid and may refer to: Leaching agriculture, the loss of water-soluble plant nutrients
Leaching is used to deionize the tubing surface through rinsing with acid solutions. Specifically, leaching solubilizes metal ions and allows them to be removed
