Background technique
Heavy metal pollution refer to the significant element of bio-toxicity (Hg, Cd, Pb, Cr and As) and with certain toxicity one
As heavy metal (elements such as Zn, Cu, Co, Ni, Sn and its compound) pollution on the environment.With rapid development of economy,
Trade effluent amount containing heavy metal ion is increasing, brings tremendous influence to environment, also endangers the health of the mankind.Such as
Metallic copper excessively will lead to red blood cell poisoning, and lead excessively will lead to nephrosis, and arsenic excessively will lead to neuritis, and cadmium excessively will lead to bone
Bone deformation, mercury excessively will lead to abalienation, and chromium excessively will lead to kidney disorder etc..It is not easy after being discharged into environment due to heavy metal
It removes, is easy accumulation in the environment, long-term toxic action can be generated to organism.Therefore, reinforce controlling heavy metal wastewater thereby
It manages the development to national economy and ensures that people's life security has a very important significance with health.
The demand of extensive use with polyallylamine in fields such as wastewater treatment, gas absorptions, polyallylamine is got over
Come bigger.However can have serious decaying chain tra nsfer phenomenon with allylamine monomers direct polymerization, and it is unable to get macromolecule
The product of amount, is prepared with method of hydrotreating, and experimentation is cumbersome.It is acidified using first being carried out to allylamine monomers herein, it eliminates
Decay chain tra nsfer phenomenon, recycles (NH4) 2S2O8 and NaHSO3 as initiator, carries out free radical to allylamine hydrochloride
Polymerization carries out ion-exchange treatment to polyallylamine hydrochloride using ion exchange resin, obtains polyallylamine.To polyene
Propyl amine carries out infrared spectroscopy and nuclear-magnetism structural characterization, the result shows that infrared spectroscopy at 997 cm ~ (- 1) corresponding C=C key and
Corresponding at 945 cm ~ (- 1)=C-H key disappears, and illustrates monomer by successful polymerization.There are 3 kinds of hydrogen on the bright C of proton magnetic spectrum chart, this
