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 adsorbent field, be specifically related to a kind of KMnO
4the corncob adsorbent of/KOH modification.
Background technology
Corncob is through strict screening, to make 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, is in use 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 be dry, pulverize, cross 60 mesh sieves.
(2) at 1%KMNO
4in the aqueous solution, add sheet KOH, pH value of solution is adjusted to 11 ~ 12.
(3) will dry corncob, add in solution, at 40 ~ 60 ℃, stir 16 ~ 24h.After stirring, with 6 mol/L HCl regulator solution pH to 6 ~ 7, use nylon net filter.Finally with deionized water washing, put at 60 ℃ of electric heating constant-temperature blowing drying boxes and dry to constant weight, make KMNO
4/ KOH modified corn core oil adsorbent.
Good effect of the present invention is: cheap, have that mechanical strength is high, pore structure is flourishing, specific area is large, adsorption rate is fast, various solutes etc. are had to 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
Below in conjunction with embodiment, describe technical scheme of the present invention in detail, but protection domain is not so limited.
1 one kinds of adsorbents of embodiment
Measure deionized water 485 ml and 30%KMNO
415 ml, pour in 1000 ml beakers and are configured to 1%KMNO
4solution.At 1%KMNO
4in solution, add sheet KOH, pH value of solution is adjusted to 11, take 10 g corncobs, add in solution, by constant temperature blender with magnetic force, stir 16h.After stirring, with 6 mol/L HCl regulator solution pH to 6, use nylon net filter.Finally with deionized water washing, put at 60 ℃ of electric heating constant-temperature blowing drying boxes and dry to constant weight, make KMNO
4/ KOH modified corn core adsorbent.Oil absorption is 14g/g.
