DT-GC-MS Analysis on Environmental Risk of Poplar Engineering Biocomposites
Poplar engineering biocomposites is a new engineering materials. In order to evaluate its potential environmental risk to human, the volatile organic compounds of poplar engineering biocomposites were adsorbed and determined by TD-GC-MS. The result were: (1) The main constituents of volatiles at 40°С were bicyclo[2.2.1]heptan-2-one, 1,7,7- trimethyl-, (1r)-(31.55%), 1,2-benzenedicarboxylic acid, mono(2-ethylhexyl) ester(14.94%), 2,6,10,14,18,22- tetracosahexaene, 2,6,10,15,19,23-hexamethyl-(7.34%), [1,1':3',1''-terphenyl]-2'-ol(5.97%), cedrol (5.29%), caryophyllene(5.26%), 3-[(1z)-1,3-butadienyl]-4-vinylcyc lopentene(3.92%), etc. (2) The main constituents of volatiles at 60°С were 1,2-benzenedicarboxylic acid, mono(2-ethylhexyl) ester(17.13%), [1,1':3',1''-terphenyl]-2'-ol(9.11%), camphor(8.6%), 4-imidazolidinone, 5-(phenylmethyl)-2-thioxo- (7.6%), cedrol(7.26%), 2,5-cyclohexadiene-1,4-dione, 2,5- diphenyl-(4.58%), 1h-indole, 5-methyl- 2-phenyl-(3.94%), 2,6,10,14,18,22-tetracosahexaene, 2,6,10,15,19,23-hexamethyl- (3.63%), phenol,2,4-bis(1,1-dimethylethyl) (3.56%), etc. So the poplar engineering biocomposites was safe under 40-60°С.
