Embodiment 4
1.1MAMC morphology analysis
Fig. 1 is the SEM figures of the mesoporous carbosphere of magnetic ferric alginate (MAMC) material prepared by the embodiment, can be with from figure
Finding out on microballoon has many irregular holes, and dispersibility is higher, and as can be seen that material surface loads from figure B
A large amount of granular object, it can be seen that iron oxide particle is intensive have been loaded in material interlayer interlayer hole, table
Bright ferric oxide particles have successfully loaded to the surface of alginate presoma, and show material iron member by EDS data
The accounting of element is 52.32% or more.
1.2 adsorption rates are tested
A concentration of 50mg/L of 25mL are added in centrifuge tube A, B, C, D, E, F of 50mL contains As (III) waste liquid, then divides
The mesoporous carbosphere of magnetic ferric alginate (MAMC) for not taking 0.125g, 0.25g, 0.5g, 0.75g, 1g, 1.25g embodiment 1 to prepare
Be added in centrifuge tube A, B, C, D, E, F, be positioned in gas bath isothermal vibration case concussion until adsorption equilibrium, 3200r/min from
It is separated by filtration after the heart, filter liquor dilution is to be measured, and the filtrate after adsorption equilibrium is measured molten using inductive coupling plasma emission spectrum
The concentration of remaining arsenic in liquid, wherein waste liquid is natrium arsenicum (Na3AsO3), sodium arsenite (NaAsO2) prepare mother liquor dilution, from
In Fig. 2 as can be seen that when test waste strength be 50mg/L when, microballoon add for 1g when, adsorption rate reaches as high as 96%
More than.
Influence of the 1.3 waste water pH values to adsorption rate
Waste liquid pH value is adjusted using the NaOH and HCl of 0.1mol/L, wherein liquid waste concentration containing As is 150mg/L, is adjusted
PH value is to 2,3,4,5,6,7,8,9,10,11, according to 1：The MAMC that 25 solid-to-liquid ratio accurately weighs the preparation of embodiment 1 is added to
In the waste water for stating different pH value, 3200rpm is centrifuged after fully shaking 24 hours, and 0.45um filter membrane mistakes are installed using injector for medical purpose
Filter, filter liquor dilution, and adsorption rate female in waste water is detected, as shown in figure 3, absorption of the MAMC materials to As (III) and As (V)
Amount is more close with the pH value relationship of solution, and for containing the waste water of As (V), acid condition is more advantageous to the absorption of material, but pH
When gradually rising, the adsorbance of unit (g) material continuously decreases, and drastically declines in pH=9, this is because the table of adsorbent
Surface charge characteristic and solute form and the pH value of solution have important relationship, when pH value is maintained between 3.0~6.0, As (V)
Ion is mainly with H2AsO4 -Form exist；When pH value is 8.0~10.5, As (V) ion is with HAsO4 2-Form exist, and
AsO4 3-Higher pH value section is appeared in, (the pH when the pH value in solution medium is more than the isoelectric pH value of MAMCPZC 6.3±
0.5) negative charge amount of material surface, can be increased, and then increases the electrostatic repulsion of material and anion, the adsorbance of As (V) can
It can significantly reduce, for containing the waste water of As (III), material is in the adsorption effect of high ph-values and low pH all unobvious；Work as solution
PH value it is relatively low when, the part ferriferous oxide on the surfaces MAMC can dissolve, to reduce the adsorption site of arsenate.With
The pH value of solution gradually rises, and the ligand absorption on metal oxide gradually increases, unionized arsenious acid (H3AsO3 0) more advantageous
In being adsorbed onto on the non-ionic site of MAMC, when pH is much larger than PZC points, hydrolysate Fe occurs for nano-iron oxide
(OH)3Electronics transfer occurs and generates Fe (OH)4 -, increase and denounceed with interionic competitive Adsorption existing for anionic form and coulomb
Power, to inhibit H2AsO3-,HAsO3 2-,AsO3 3-The absorption of the anionic forms such as equal arsenates.
1.4MAMC pore-size distributions and BHJ and thermal stability analysis
The results are shown in Figure 4 by being obtained to the BET of MAMC materials analysis and pore analysis, and the specific surface area of MAMC is about
For 62.583m2The pore analysis result of/g, material are Pore Size=12.96nm, in a nitrogen environment, by changing pressure
And the adsorption and desorption curve of material is depicted using BJH methods, it can obviously observe hysteresis loop at 0.63P/P0Place occurs, compared with
High relative pressure region MAMC does not show any absorption limitation, illustrates that MAMC is that a kind of absorption property is superior, gap and ratio
The more flourishing mesoporous material in surface；
The MAMC materials for taking 3.2mg embodiments to prepare, in a nitrogen environment with the heating rate test material of 10 DEG C/min
Thermal stability, the results are shown in Figure 5, at a temperature of 0 DEG C~300 DEG C be pyrolyzed phenomenon it is more gentle, material still keeps preferable
Thermal stability, but sodium alginate embedding forerunner is volatilized by thermal decomposition when temperature reaches 400 DEG C or more, causes the pyrolysis speed of material
Rate increases.
1.5MAMC material regenerations are analyzed
MAMC materials of the NaOH to absorption As (III) and As (V) of 0.01mol/L, 0.1mol/L, 1mol/L is respectively adopted
It is desorbed and is regenerated, the results showed that use the NaOH of 0.1mol/L ideal as the desorption and actified solution of material, material
Material is maintained to 90% and 60% or more the removal effect of As (III) and As (V) after carrying out four desorptions, it was demonstrated that
MAMC can realize multiple recycling, be preferable green sorbing material.
The above embodiments and description only illustrate the principle of the present invention and most preferred embodiment, is not departing from this
Under the premise of spirit and range, various changes and improvements may be made to the invention, these changes and improvements both fall within requirement and protect
In the scope of the invention of shield.
