The process of change for thermo-oxidative degradation of latex film at different vulcanization time during the prevulcanization of latex by peroxide was studied by using of TG-DTG and DTA.
The application of surfactant in microbial degradation of petroleum pollution in recent years is introduced in this paper and the factors of choosing the eptitude surfactant are also disc.
When the illuminance rose, the photic decomposition rates of the natural anthocyan pigments rose as well, but there was no linear relation between photic decomposition rate and illuminance.
Furthermore, through SDS-PAGE analysis, the cold shock treatment was found able to delay the discomposition of proteins, hence to raise the tolerance of CI of Nai-plum fruit.
The changes in chemical structure of residual lignin in reed kraft pulp after treatment with a white rot fungus,Panus conchatus have been investigated in the present paper.
The result indicates that the main metabolic product of petroleum hydrocarbon degradation is acetic acid and surface active agent of glycolipid composed of fatty acid and rhamnose.
Moreover, it was shown that degradation of lignin was promoted by veratryl alcohol added, no effect of veratryl alco-hol on degradation of cellulose and hemicellulose was detected.
Bio - degradation role of aerobiotic organic substance and relationships between biological degradation and dissolved oxygen were stated, which provided theoretical basis for waste water reatment.
Nonbiodegradable pollutants, such as certain chlorinated hydrocarbon pesticides (e.g.DDT) and heavy metals, such as lead, copper, and zinc in some industrial effluents, accumulate in the environment.
On the basis of mechanism analysis and compare of CODCr degradation rate, parachlorophenol and aniline were found to be easier degraded by ferrate than nitrobenzene.
This paper briefs the industrial usages i and harmfulness of cyclopentanone and cyclohexanone, and reviews the research progresses in microbial degradation of cyclopentanone and cyclohexanone.
Alright the next dopamine-directed class of therapies are inhibitors of COMT, catecholamine-O-methyltransferase, which is an enzyme that degrades dopamine and levodopa.
After the kelp grows, the biodegradable buoy will dissolve and loses it buoyancy and by then the kelp is so heavy that it sinks to the ocean bottom, sequestering the carbon for a thousand plus years.
The same Thomson Reuters report I told you about earlier says that by 2025 biodegradable materials based on cellulose will replace plastic packaging for all purposes.
They're estimated after seeing how many samples of a drug degrade over short periods of time, or by accelerating the breakdown of the drug's active ingredients.
