Natural fiber environment-friendly adsorption material and method for preparing same

Abstract

The invention provides a natural fiber environment-friendly adsorption material and a method for preparing the same.The method includes steps of mixing carboxymethyl celluloses, carboxymethyl hydroxyethyl celluloses, carboxymethyl hydroxypropyl celluloses, sodium cellulose sulfate, sodium alginate and 60-70 parts of water with one another to obtain first mixtures; slowly stirring the mixtures by the aid of glass rods and then stirring the first mixtures by the aid of a magnetic stirrer; adding glyoxylic acid, sodium hydroxide and 20-30 parts of water into the first mixtures, increasing the temperatures and then carrying out reaction; washing filter materials and then freezing and drying the filter materials; adding palm wax, phosphatidylinositol, starch sugar alcohol, carnosol, squalane, chitosan and remaining water into the filter materials to obtain second mixtures; stirring the second mixtures by the aid of the magnetic stirrer; adding ethylene oxide into the second mixtures; stirring the ethylene oxide and the second mixtures by the aid of the magnetic stirrer to obtain third mixtures; reducing the rotational speed of the magnetic stirrer and stirring the third mixtures; filtering the third mixtures and then washing the third mixtures until the third mixtures are neutral; drying the third mixtures and then grinding the third mixtures to obtain powder.The natural fiber environment-friendly adsorption material and the method have the advantages that the natural fiber environment-friendly adsorption material is degradable, and excellent adsorption effects can be realized by the natural fiber environment-friendly adsorption material for heavy metal ions.

Description

technical field [0001] The invention relates to the field of materials, in particular to a natural fiber environmental protection adsorption material and a preparation method thereof. Background technique [0002] With the progress of society and the rapid development of economy, coupled with the rapid increase of population, the natural environment on which human beings depend has been polluted and destroyed to varying degrees, among which water pollution is particularly serious. The annual discharge of wastewater in my country is more than 100 million tons. These wastewater mainly come from industries such as chemical industry, oil refining, metal manufacturing, mining, textile and agriculture, and accumulate a large amount of heavy metal ions, such as copper, lead, cadmium, chromium and arsenic ions. . And some wastewater is directly discharged into the water body without any treatment. Since heavy metal ions cannot or are rarely metabolized by the human body, they have a...

Problems solved by technology

And some wastewater is directly discharged into the water body without any treatment. Since heavy metal ions cannot or are rarely metabolized by the human body, they have an enrichment effect, which has caused great harm to human health, animal and plant survival.
