Witryna20 godz. temu · NaOH is the strong base used in popular industries due to multiple functions. It is used as an excellent catalyst for many different processes. It has diverse applications in the field of the papermaking industry, textile industry, soap and detergent, aluminum extraction and food additives, etc. Witryna21 cze 2024 · An acid-base extraction is a type of liquid-liquid extraction. It typically involves different solubility levels in water and an organic solvent. The organic solvent may be any carbon-based liqiuid that does not dissolve very well in water; common ones are ether, ethyl acetate, or dichloromethane.
Witryna9 lis 2024 · In general, dilute alkaline solutions, specifically NaOH, can extract up to 80% of SOM from mineral soils (Stevenson, 1994). In addition to Ca 2+, other polyvalent cations such as aluminum (Al 3+) and ferric (Fe 3+) ions are responsible for maintaining OM in an aggregated and insoluble condition (Posner, 1966).
