Abstract
The invention discloses adsorbent, which is a corncob modified by KMO4/KOH, is characterized by low cost, high mechanical strength, developed pore structure, large specific surface area, fast rate of adsorption, and excellent adsorption capacity to various solutes, is suitable for deodorizing, dechlorinating and decoloring highly purified drinking water, beverages, liquors, foods and medicine, and moreover, is widely used for petroleum adsorption and the like.
Description
Technical field
The present invention relates to the adsorbent field, be specifically related to a kind of KMnO
4The corncob adsorbent of/KOH modification.
Background technology
Corncob is to make through strict screening with the broken processing of corn ear again, has the advantages such as even tissue, hardness are suitable, good toughness, water imbibition is strong, anti-wear performance is good, in use is difficult for fragmentation.Because corncob contains abundant cellulose, hemicellulose, lignin etc., available it from waste water, extract heavy metal.
Summary of the invention
The object of the invention is to adopt KMnO
4The corncob adsorbent of/KOH modification.
Described KMnO
4The preparation process of the corncob adsorbent of/KOH modification is:
(1) corncob is dry, pulverize, cross 60 mesh sieves.
(2) at 1%KMNO
4Add sheet KOH in the aqueous solution, pH value of solution is transferred to 11 ~ 12.
(3) will dry corncob, add in the solution, at 40 ~ 60 ℃ of lower 16 ~ 24h that stir.After the stirring, with 6 mol/L HCl regulator solution pH to 6 ~ 7, use nylon net filter.At last with deionized water washing, put under 60 ℃ of the electric heating constant-temperature blowing drying boxes and dry to constant weight, namely make KMNO
4/ KOH modified corn core oil adsorbent.
Good effect of the present invention is: cheap, have the mechanical strength height, pore structure is flourishing, specific area is large, adsorption rate is fast, various solutes etc. are had good adsorption capacity, be applicable to deodorizing, dechlorination and the liquid decoloration of high purity drinking water, beverage, drinks, food and medicine, and can be widely used in oil absorption etc.
The specific embodiment
Describe technical scheme of the present invention in detail below in conjunction with embodiment, but protection domain is not so limited.
