Embodiment Construction

[0030] The direction terms mentioned in the present invention, such as up, down, top, bottom, front, back, left, right, inside, outside, side, around, center, horizontal, transverse, vertical, longitudinal, axial, radial, The uppermost layer, the lowermost layer, and the like are merely directions referring to the attached drawings. In addition, the singular forms "a", "an" and "the" mentioned in the present invention include plural references, unless the context clearly dictates otherwise. For example, the term "a compound" or "at least one compound" may include multiple compounds, including mixtures thereof; "%" mentioned in the present invention refers to "weight percent (wt%)" unless otherwise specified; numerical range (such as 10% to 11% of A) if there is no specific description, both upper and lower limits are included (ie 10%≦A≦11%); if the value range does not define the lower limit (such as B below 0.2%, or B) below 0.2% means that the lower limit may be 0 (that is,...

Abstract

The invention discloses compound particles and a method for managing heavy metal pollutants. Each compound particle is prepared from a nano metal kernel and a modification surface layer for covering the nano metal kernel. Each modification surface layer has at least one coordinated functional group and a metal complex compound is formed by the coordinated functional group and a heavy metal ion, so that contact between the heavy metal ion and the compound particles is easy to realize. Each nano metal kernel takes an iron nanoparticle as a main component and is used for rapidly and continuously reducing the heavy metal ion; furthermore, each nano metal kernel contains aluminum nanoparticles and nickel nanoparticles and the anti-corrosion property and stability of the compound particles are improved.

Description

technical field [0001] The present invention relates to a composite particle for remediating heavy metal pollutants and a method thereof, in particular to a composite particle for remediating heavy metal pollutants capable of absorbing and further reducing heavy metal ions and a method for using the same. Background technique [0002] With the rapid development of industry and the excessive use of heavy metals, the seepage water of industrial waste liquid and unidentified waste dump sites contains heavy metals that cannot be loaded by the environment. Different raw materials and power are used in various industrial methods, and the amount and quality of the wastewater produced are extremely complex, especially the wastewater containing heavy metals, which will affect the ecology of the water body after being discharged into the river, and further affect agricultural irrigation. Water and water for people's livelihood. If people drink water containing heavy metals for a long...
