Iron (Fe) metal is often found in well water and at high concentrations can degrade water quality. This study synthesized a Biochar/MnFe₂O₄/Ag₃PO₄ composite, evaluated its characteristics, Fe adsorption capacity, and applied it to well water and antibacterial tests. Biochar was synthesized through pyrolysis of rice husk, MnFe₂O₄ was modified through coprecipitation, and followed by …
The limitations of the physical properties of ultisol soil, particularly porosity and low water-holding capacity, are one of the main constraints in cultivating vegetable crops, such as spinach (Amaranthus sp.). Efforts to improve these conditions can be carried out through the application of rice husk Biochar as an ameliorant material and by regulating the appropriate watering frequency to inc…
