5th, adsorption test result
5.1st, BLB, PSB and PPB particle is to Pb2+Absorption
The result of experiment 3.1 is as shown in Figure 1.
As seen from Figure 1, BLB is to Pb in water2+There is certain adsorption capacity, this is because the sodium alginate contained in BLB
The heavy metal ion in water can be adsorbed.PSB and PPB are to Pb2+Adsorption rate is significantly larger than BLB, thus infers that addition great Piao powder has
Increase to effect the adsorption capacity of BLB.Disposable foam cutlery box is added to prepare PPB, the increase of particle mechanical strength, early stage in PSB
Observation shaping is preferable, even particle size, and oscillatory process is not broken in adsorption experiment, tests in follow-up repeatedly absorption-desorption
Middle grain shape is still remained intact.Because PPB has good absorption property and mechanical strength, below test and made using PPB
For adsorbent.
5.2nd, PPB dosages are to adsorbing Pb2+Impact
The result of experiment 3.2 is as shown in Figure 2.
As seen from Figure 2, in the Pb that 50mL concentration is 100mg/L2+In solution, when PPB dosages are less than 1.5g, with
The increase of dosage to Pb2+Adsorption rate increases rapidly；When dosage increases to 3.5g from 1.5g, continue to increase dosage pair
Adsorption rate affects less, and adsorption rate amplification tends towards stability.From ensureing adsorption effect, and cost-effective angle, subsequent experimental PPB
Dosage is 1g.
5.3rd, temperature adsorbs Pb to PPB2+Impact
The result of experiment 3.3 is as shown in Figure 3.
From the figure 3, it may be seen that in certain temperature range, the higher absorption of temperature is better, illustrates PPB to Pb2+Adsorption process may
It is the endothermic reaction.Under the conditions of due to 25 DEG C of room temperature, adsorption rate is up to more than 82%, it is contemplated that the situation of change of daily temperature, with
And to realize energy-saving and emission-reduction, it is proposed that adsorption reaction is controlled more than 25 DEG C.This experiment is carried out in Guangdong autumn, and room temperature is about
25 DEG C, therefore experiment is under room temperature and carries out.
5.4th, adsorption time adsorbs Pb to PPB2+Impact
The result of experiment 3.4 is as shown in Figure 4.
As shown in figure 4, with the prolongation of adsorption time, PPB is to Pb2+Absorption first rapid increase be presented then tend to flat
It is slow.When adsorption time is less than 2h, as time went on adsorption rate is rapidly increased to 82%；Then continue to extend adsorption time extremely
6h, adsorption rate increasess slowly, and only increases to 94% by 82%.Therefore, adsorption time is suitably controlled in 2h.
As shown in figure 4, reaction temperature is higher, the early stage rate of adsorption is faster.React 2h under the conditions of 10 DEG C and 25 DEG C respectively
Adsorption rate difference is 10.9%.But when the time 6h is extended to, adsorption rate gap is contracted to 0.8% under the conditions of two temperatures.It can be seen that,
Be conducive to improving adsorption rate by extending the reaction time.
5.5、Pb2+Initial concentration adsorbs Pb to PPB2+Impact
The result of experiment 3.5 is as shown in Figure 5.
As shown in Figure 5, as heavy metal initial concentration increases, PPB is to Pb2+Adsorption rate is presented downward trend, and temperature
Higher, adsorption rate increases with concentration and fall is bigger.When temperature is 40 DEG C, Pb2+Initial concentration 15mg/L is increased to
300mg/L, then adsorption rate decline 29.9%.Therefore, PPB is properly applied to the adsorption treatment of low concentration heavy metal water.
5.6th, solution initial pH value adsorbs Pb to PPB2+Impact
The result of experiment 3.6 is as shown in Figure 6.
It will be appreciated from fig. 6 that when solution initial pH value≤4, adsorption rate is 67%～70%.When solution initial pH value is increased to
When 5, adsorption rate increases to rapidly 84.3%.Solution initial pH value affects PPB to Pb2+Absorption property, pH value control more than 5
Most preferably.
6th, circulation absorption result of the test
The result of experiment 4 is as shown in Figure 7.
As shown in Figure 7, by absorption-desorption-adsorb again, PPB is to Pb2+The 2nd adsorption rate than the 1st time decline 13 hundred
Branch, it is seen that Pb2+Combined with PPB relatively closely, be difficult desorption.But the 2nd absorption-desorption-adsorb again, PPB is to Pb2+Absorption
Rate declines not substantially, and the 3rd time adsorption rate only declines 2.6% than the 2nd time.It is considered that PPB particles are through multiple circulation absorption-solution
Suction still keeps certain adsorption capacity, can inquire into follow-up research and its desorption effect how is improved under the conditions of optimal desorption
Rate, to strengthen recycling efficiency.
7th, conclusion (of pressure testing)
The present invention adopts disposable foam cutlery box, dried great Piao plant powders, sodium alginate and polyvinyl alcohol reagent
Prepare solid particle, the immobilized biological adsorbent particle of acquisition, the particle has good absorption property and a mechanical strength, 60
6h adsorption rates are reacted under the conditions of DEG C up to 100%.Through 3 absorption-desorptions-adsorb again, grain shape keeps complete, and adsorbs
Rate is still more than 68%.PPB be a kind of with low cost, material source extensively, advantages of good adsorption effect, possess and recycle the new of performance
Type adsorbent, has stronger using value in heavy metal containing wastewater treatment.
The better embodiment of the present invention is explained in detail above, but the present invention is not limited to above-mentioned embodiment party
Formula, in the ken that one skilled in the relevant art possesses, can be with the premise of without departing from present inventive concept
Various changes can be made.
