APPLICATIONS OF ANION EXCHANGER MINERALS THAT SET NO3- REVERSIBLY.

摘要

Use of double laminated hydroxides (LDH), which reversibly exchange NO3-, as fertilizer and soil improvement substances for the uniform supply of nitrate-shaped nitrogen-cultivated soils, containing LDH in the interchangeably fixed anion intermediate layers and can be represented by the following formula: M (1-x) M¿x (OH) 2 x (An- x / n) mH2O meaning M a divalent metal ion or 2 Li, M¿ a trivalent metal ion, An anion n -valent fixed in the intermediate layer.
