Preparation and Performance Evaluation of Novel Molecularly Imprinted Polymers for Environmental Pollutant Monitoring
摘要
Abstract
In order to improve the monitoring efficiency of sulfonylurea pesticides in water environments,a novel molecularly imprinted polymer suitable for environmental pollutant monitoring was prepared using methyl iodosulfonate and methyl disulfonate as dual template molecules,4-vinylpyridine(4-VP)as functional monomer,diphenylmethane diisocyanate(MDI)as crosslinking agent,and acetonitrile(ACN)as pore forming agent.The preparation conditions were optimized indoors,and its thermal stability and adsorption properties were evaluated.The results showed that when the molar ratio of template molecules,functional monomers,and crosslinking agents was 1:2:20,the novel molecularly imprinted polymer exhibited better adsorption effects on methyl iodosulfonate and methyl disulfonate.The new molecularly imprinted polymer also has good thermal stability,and its mass loss rate is relatively small at temperature not exceeding 320℃.In addition,the new molecularly imprinted polymer has good static adsorption and class specific adsorption properties for sulfonylurea pesticides.As the initial mass concentration of methyl iodosulfonate and methyl disulfonate increased,the adsorption capacity gradually increased;And under the same experimental conditions,the adsorption capacity of the new molecularly imprinted polymer for sulfonylurea pesticides was significantly higher than that of other types of pesticides,indicating strong selectivity.关键词
