| titleOfInvention | It is a kind of that there is Cation adsorption and the difunctional biological carbon microspheres of fertilizer control release and preparation method thereof |
| abstract | The invention discloses a kind of with Cation adsorption and the difunctional biological carbon microspheres of fertilizer control release and preparation method thereof, including：(1) two parts of carboxymethyl chitosan solutions are prepared, portion is shell solution, and addition humic acid, dimethyl sulfoxide (DMSO) and potassium nitrate, stir, be used as stratum nucleare solution in another；(2) shell solution and stratum nucleare solution are injected separately into the outer layer and internal layer of coaxial syringe needle, and shell solution and stratum nucleare solution are ejected into epoxychloropropane solution using high-pressure electrostatic spinning equipment, stir, filtering, dry, the Crosslinked Carboxymethyl Chitosan Microsphere of core shell structure is made；(3) Crosslinked Carboxymethyl Chitosan Microsphere is placed in tube furnace, leads to nitrogen protection, biology carbon microspheres are made in roasting.Biological carbon microspheres prepared by the present invention can be used as release and release control fertilizer, improves utilization rate of fertilizer, power is provided for the restoration of the ecosystem of plant；And material can be widely applied to the absorption of the cation such as uranyl radical ion, lead ion and wastewater treatment in the fields such as chemical industry and environmental protection in itself. |
