Description
Technical field
The present invention relates to the embedding method of adsorbent for heavy metal poly m-phenylene diamine, relate in particular to a kind of adsorbent of poly m-phenylene diamine, Its Preparation Method And Use with sodium alginate to embed.
Background technology
Embedding medium commonly used has sodium alginate, polyvinyl alcohol, polyacrylamide, gelatin, carragheen etc.Wherein sodium alginate is as a kind of natural polymer carrier, and is cheap, is to use one of fixation support material more widely.Its embedding principle be wherein sodium ion by exchanging with heavy metal ion such as calcium ion, the linear macromolecule chain takes place crosslinked by calcium ion, form crosslinked calcium alginate gel network structure, thereby Powdered adsorbent is embedded in wherein.The calcium alginate gel bead mass-transfer performance of Xing Chenging is good like this.Calcium alginate also can keep mechanical performance preferably as fixation support intensity height in strong electrolyte solution, and can the very wide pH scope of tolerance range, adapts to the requirement of wastewater treatment in the industrial production.Because sodium alginate is nontoxic, the nontoxic usefulness that turns into of living beings such as pair cell, therefore, sodium alginate is used for pair cell and microbial immobilization embedding more, and the embedding of adsorbent for heavy metal is seen in the also few of report.There is the researcher to use sodium alginate and gelatin cross-blend thing to come the fixedly mould fungi of adsorbents for lead ion pyrolytic branch spore of embedding, the embedding bead can reach 74.57mg/g at plumbum ion concentration during for 150mg/L to the adsorbance of lead waste water, and the mould corresponding adsorption capacity of not immobilized branch spore is 70mg/g (Dong Xinjiao, Zhu Cong. the immobilization fungi is to the research of the biological absorption of lead ion. environmental science and technology and technology .2005,28 (6): 22-27).This author has also provided the report of pure this fungi of employing sodium alginate to embed.The report that utilizes the sodium alginate to embed mercury ion adsorbent is also arranged, a kind of mercury ion adsorbent suspends after algae utilizes the calcium alginate gel embedding one by one, concentration is respectively 0.2,0.8, the mercury ion sewage static treatment of 1.4 μ g/L 5 days, the mercury ion clearance is respectively 94.7%, 94.5% and 97.5%, and the corresponding clearance of embedding suspension algae is not respectively 79.7%, 88.1% and 76.9% (tight Guoan, Li Yijian. the .1994 of Research of Environmental Sciences, 7 (1): 39-42).As seen, embedding medium sodium alginate itself also has contribution to the heavy metal ion ionic adsorption, and this mainly is to form gel because the hydroxy-acid group on the sodium alginate strand can interact with heavy metal ion, thereby with complexing of metal ion wherein.
But the research of the adsorbent of poly m-phenylene diamine of relevant use sodium alginate to embed does not see that as yet report is arranged.
Summary of the invention
Purpose of the present invention just provides a kind of operate adsorbent of poly m-phenylene diamine and its preparation method thereof with sodium alginate to embed simple and easy, with low cost.
For realizing above purpose, the present invention is achieved through the following technical solutions:
With the adsorbent of poly m-phenylene diamine of sodium alginate to embed, its component comprises poly m-phenylene diamine and sodium alginate, the sodium alginate to embed poly m-phenylene diamine, and the weight ratio of poly m-phenylene diamine and sodium alginate is 0.5～2:1.
A kind of method for preparing with the adsorbent of poly m-phenylene diamine of sodium alginate to embed, weight ratio according to poly m-phenylene diamine and sodium alginate is 0.5～2:1, it is to make mixed solution in 2%～4% sodium alginate aqueous solution that poly m-phenylene diamine is added weight content, mixed solution being extruded into bead, to splash into weight content be in 3%～5% the calcium chloride water again, reacted the calcium chloride on flush away bead surface 18～40 hours.
Preferably, before mixed solution is extruded into bead,, mixed solution is mixed earlier with the ultrasonic processing of mixed solution 5-25 minute.
The adsorbent of poly m-phenylene diamine with sodium alginate to embed among the present invention can be used as Adsorption of Heavy Metal Ions, especially as adsorpting lead ion.
The prepared breakage rate with the adsorbent of poly m-phenylene diamine of sodium alginate to embed of the present invention adopts following method to measure:
Accurately taking by weighing 0.10g is put in the 50mL distilled water with the adsorbent of poly m-phenylene diamine bead of sodium alginate to embed, in 30 ℃ water bath with thermostatic control, stir 24h, filter, take out and weigh after intact bead dries naturally, calculate breakage rate according to the weight change before and after handling.Get its mean value by twice parallel laboratory test.
The absorption property of using the adsorbent of poly m-phenylene diamine of sodium alginate to embed to lead ion of the present invention adopts static adsorptive method to detect, and concrete steps are as follows:
Take by weighing and contain 50mg with the adsorbent of poly m-phenylene diamine bead of sodium alginate to embed, place that to contain 25mL-100mL concentration be 511.78mgL
-1The conical flask of lead nitrate solution in, at 20-40 ℃ of following stirring and adsorbing 1-30 hour, filter, with remaining Pb in the complexometric titration filtrate
2+Concentration C '.Calculate adsorbents adsorb capacity Q (mg g respectively according to formula (1) and (2)
-1) and clearance q (%).
Beneficial effect of the present invention: utilize the sodium alginate to embed poly m-phenylene diamine to become the adsorbent bead, operation is simple, with low cost.Bead satisfactory mechanical property after the embedding, bead intensity can satisfy the continued operation under the adsorption conditions, and promotes to some extent with the adsorbent of poly m-phenylene diamine of the sodium alginate to embed absorption property with respect to poly m-phenylene diamine.Take all factors into consideration cost of material, cost of manufacture and absorption property, have very big potential actual application value with the adsorbent of poly m-phenylene diamine of sodium alginate to embed.
