Preparing method of hydrochar stabilizers based on wood waste comprising magnesium ferrite nanoparticles and Stabilization method for contaminated soil comprising arsenic and cation mixed using thereof

摘要

In the present invention, unlike the biochar manufacturing method according to the pyrolysis (~ 1000 ℃) according to the prior art, the reaction is carried out at a relatively low temperature (180 ~ 300 ℃), and also separate drying because water is used as a catalyst It does not require a process, so it is possible to produce a hydrocar loaded with magnesium ferrite nanoparticles with high energy efficiency, high specific surface area and high cation exchange capacity through a one-pot reaction relatively simply and conveniently. A method for manufacturing a lignocellulosic waste-based hydro tea in which magnesium ferrite nanoparticles are supported, and a lignocellulosic waste-based hydro tea prepared according to the above method in which magnesium ferrite nanoparticles are supported, and a method for stabilizing soil contaminated with arsenic and cationic heavy metal complex using the same is about
