Recommanded Product: 1-Phenylurea. Recently I am researching about PERFORMANCE LIQUID-CHROMATOGRAPHY; ENVIRONMENTAL WATER; GAS-CHROMATOGRAPHY; MILK SAMPLES; MICROEXTRACTION; SPECTROMETRY; CARBON; DIURON; BIOSENSORS; IONS, Saw an article supported by the National Natural Science Foundation of ChinaNational Natural Science Foundation of China (NSFC) [31571925, 31671930]; Natural Science Foundation of Hebei ProvinceNatural Science Foundation of Hebei Province [B2016204136, B2016204146, B2017204025, C2018204076]; Preferential Foundation for the Introduction of Overseas Scholars by Hebei Province [CL201713]; Natural Science Foundation of Hebei Agricultural University [LG201607, LG201610, ZD201703, LG201712]. Published in SPRINGER WIEN in WIEN ,Authors: Guo, LY; Hao, L; Gao, T; Wang, C; Wu, QH; Wang, Z. The CAS is 64-10-8. Through research, I have a further understanding and discovery of 1-Phenylurea
Graphene oxide was covalently modified with p-phenylenediamine via a diazonium reaction. The resulting material was employed as a sorbent for the solid-phase extraction of six phenylurea herbicides (metoxuron, monuron, chlortoluron, isoproturon, monolinuron, and buturon) from environmental water and lettuce leafs. Some key factors that influence the extraction efficiency were studied, including sample loading rate, sample pH, and desorption conditions. Following desorption with acetonitrile, the analytes were quantified by HPLC with UV detection. Under optimized conditions, response to phenylurea herbicides is linear in the 2.0-100ngmL(-1) concentration range for water samples, and 5.0-100ngg(-1) for leaf lettuces. The limits of detection are 0.10-0.25ngmL(-1) for water samples, and 1.5-2.5ngg(-1) for leaf lettuces. The sorbent was also applied to the preconcentration of organic compounds including nitroimidazoles, chlorophenols, phenylurea insecticides and phthalates. This shows that this sorbent has a large potential for the enrichment of organic pollutants.
