Abstract

The invention relates to a method for preparing the silicane coupling nanometer magnetic compound ferriferrous oxide. First dissolving the divalent and trivalent ferric salt in the water; protected by the inert gases, adding alkali solution to alkalescence; heating and mixing to attain the nanometer ferriferrous oxide particle; adding the diffusion solvent and silicane coupling agent to be heated and mixed to attain the final product. The invention can be used in the detection of left matter of environment last contamination. The inventive method has simple process, lower cost, and the product has uniform distributed nanometer magnetic compound ferriferrous oxide, and when it is used in the detection of left matter of environment last contamination, it has better repeating property, and the material can be recycled.

Description

technical field

[0001] The invention relates to a method for manufacturing nanomaterials, in particular, the invention relates to a method for preparing a silane-coupled nano-magnetic composite ferric oxide material. technical background

[0002] Nano-magnetic composite materials are inorganic or organic composite materials formed by wrapping one or more hydrophobic or hydrophilic groups with nano-magnetic particles as the core through interactions such as bonding, coupling, and adsorption. Fe 3 o 4 Nano-magnetic composite materials are based on nano-Fe 3 o 4 A class of nano-magnetic composite materials for the core. Due to its diverse preparation methods, relatively easy control of the process, predictability, controllability and tailorability of structure and function, and wide application, it has gradually become a research hotspot of scientists at home and abroad.

[0003] Fe 3 o 4 The preparation of nano-magnetic composite materials is mainly divided into two ste...
