Problems solved by technology

Activated carbon can effectively remove free chlorine in water and can effectively absorb organic pollutants such as color, odor, pesticides, insecticides, detergents, aromatic compounds, and disinfection by-products (DBPs) in water. A large amount of organic matter adsorbed on the surface of activated carbon becomes a breeding ground for bacteria, which easily leads to excessive bacterial content in the effluent, resulting in problems of short service life and bacterial growth, and the removal effect of activated carbon on heavy metal ions in water is not good
Its disadvantage is that the current KDF is only a simple copper and zinc alloy material, and the area in contact with water is very limited when purifying water, so the water treatment e

Abstract

The present invention relates to polynary metal cluster as water purifying material and its preparation process and use. The water purifying material is prepared with porous material in 50-99 wt%, and two or more metals of Ag, Cu, Zn and RE in 1-50 wt%. The preparation process includes: selecting metal source; adding the metal source directly or after being compounded into water solution into the porous material to form combined body; and introducing reductant after roasting. Water to be purified is made to flow through the water purifying material or mixed with the water purifying material for purifying. The water purifying material has great specific surface area, high activity and high homogeneity, and may be used to eliminate water soluble heavy metal ion, micro organic pollutant, residual chlorine and sterilizing side product in high effect.

Description

technical field [0001] The invention relates to a water purification material, in particular to a novel nanometer multi-element metal cluster water purification material. [0002] The invention also relates to the preparation method and application of the water purification material. Background technique [0003] With the development of society and the improvement of living standards, people's requirements for quality of life are getting higher and higher. The impact of clean and safe drinking water on people's quality of life cannot be ignored. Water is the main carrier for the transmission of various germs, and 80% of human diseases are related to water pollution. Access to clean and safe drinking water has become a worldwide issue. On the other hand, water pollution is becoming more and more serious. Surface water such as rivers and lakes and groundwater in some areas are polluted to varying degrees. The problem of water shortage has attracted widespread attention. ...
