Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
A kind of preparation method and adsorption applications based on house refuse charcoal adsorbent material comprising following steps:
(1), pre-process: by waste wool hair sample be put into beaker, be added inorganic agent, be cleaned by ultrasonic 2min (twice), spend from
Sub- water is rinsed well, is placed in Constant Temp. Oven, and the waste wool hair clipper after 37 DEG C of dry 8h, drying are broken, obtains processed material,
Wherein, inorganic agent is the HCL of 0.1mol/L.
The present invention pre-processes waste wool hair using the HCL inorganic agent of 0.1mol/L, the reason is as follows that:
In air due to hair exposure, and certain hair dyeing hair-waving, complicated component, simultaneously containing a large amount of metal members are mixed with
Element can significantly reduce content such as Zn, Mg, Mn, Cd of metallic element etc., reduced cigarette after the HCL microwave cleaning of 0.1mol/L
Gas pollution, improves the purity of charcoal adsorbent material.
(2), carbonization: by step (1) resulting processed material with the heating speed of 5 DEG C/min under the protection of inert gas
Rate is warming up to 200-450 DEG C, carbonizes 0.5-2h, obtains powdered charcoal adsorbent material.Wherein, inert gas is nitrogen, flow
For 50-250mL/min.
It is needed to improve the yield of fibrous charcoal (i.e. solid matter) lower according to the principle of pyrolysis charring
Heating rate under carry out, therefore will heat up rate the characteristics of bonding apparatus and be determined as 5 DEG C/min.
By measurement it is found that the yield of prepared powdered charcoal adsorbent material is 37-72%, phosphorus content 60.1-
70.2%, iodine sorption value 1300-2500mg/g, and three is related with the temperature of carbonization reaction, and carbonization temperature is lower, charcoal
The yield of adsorbent material is higher, and phosphorus content is lower, and iodine sorption value also accordingly becomes smaller, and illustrates that charcoal adsorbent material adsorption capacity reduces,
So carbonization temperature is determined as 200-450 DEG C, it can be preferably 250-350 DEG C.Charcoal adsorbent material iodine sorption value with higher,
Illustrate that it has flourishing micropore and very strong adsorption capacity.
(3), adsorption applications: the powdered charcoal adsorbent material obtained according to above-mentioned preparation method is to heavy metal in waste water Ni
(II) adsorption applications method is as follows: at 30 DEG C of adsorption temp, nature pH, charcoal adsorbent material is to 40-60mg/L initial concentration
Ni (II) solution is adsorbed from 0-240min, obtains heavy metal in waste water Ni (II) adsorption dynamics curve.
When heavy metal in waste water Ni (II) initial concentration rises to 60mg/L from 40mg/L, obtained at 350 DEG C of carbonization temperature
Charcoal adsorbent material heavy metal Ni (II) adsorptive value is continuously increased, and show similar adsorption dynamics adsorption kinetics behavior.From 0-
In 120min, adsorbance is increased rapidly as the time increases；In 120-180min, adsorbance slowly increases increase with time；
After 180min, absorption tends towards stability, and adsorbance no longer increases absorption substantially and reaches balance.It is real when initial concentration is 40-60mg/L
It is 4.65-6.25mg/g that test, which obtains equilibrium adsorption capacity,.The result shows that having with charcoal adsorbent material to heavy metal in waste water Ni (II)
Absorption property.
In addition, charcoal adsorbent material produced by the present invention can be applied to the fields such as plant culture, soil improvement or soil water-retaining
Or it reapplies after absorption pollutant in fields such as plant culture, soil improvement or soil water-retainings.
Below in conjunction with comparative example and embodiment, the present invention is further illustrated.
