摘要: Layered Double Hydroxide (LDH) intercalated with phosphate ions (LDH-phosphate) was synthesized by ion-exchange method from a precursor containing nitrate between the layers. The materials were characterized X-ray diffraction (XRD), attenuated total reflectance–Fourier transform infrared spectroscopy (ATR-FTIR), thermogravimetric analysis coupled to differential scanning calorimetry and mass spectrometry (TGA-DSC-MS), specific surface area (BET), electron microscopy (SEM), elemental analysis. We hypothesized that LDH-phosphate can be used as slow release fertilizer help increase fertilization efficiency in tropical weathered soils. This new technology tested kinetic study of P bioassay controlled conditions light, humidity, temperature using maize (Zea mays) our indicator plant. performed an adaptation Neubauer method, wherein compared commercial triple superphos...
