The systematic study of pyrimidines began in 1884 with Pinner, who synthesized derivatives by condensing ethyl acetoacetate with amidines. Pinner first proposed the name “pyrimidin” in 1885. 109-12-6, formula is C4H5N3, Name is Pyrimidin-2-amine. The parent compound was first prepared by Gabriel and Colman in 1900, by conversion of barbituric acid to 2,4,6-trichloropyrimidine followed by reduction using zinc dust in hot water. Name: Pyrimidin-2-amine.
Ma, Dongmei;Yang, Yang;Liu, Bingfeng;Xie, Guojun;Chen, Chuan;Ren, Nanqi;Xing, Defeng research published 《 Zero-valent iron and biochar composite with high specific surface area via K2FeO4 fabrication enhances sulfadiazine removal by persulfate activation》, the research content is summarized as follows. Zero-valent iron and biochar composite (ZVI/BC) is a prospective catalyst for activating persulfate and sp. surface area (SSA) of ZVI/BC is one of the most important factors affecting its efficacy in the removal of environmental contaminants. However, the green fabrication of ZVI/BC with large SSA remains a challenge. In this study, ZVI/BC with a highly porous structure and large SSA fabricated by co-pyrolysis of K2FeO4 and bamboo was prepared and characterized. The large SSA stemmed from the catalytic and corrosive functions of K and the oxidation of K2FeO4 onto bamboo. ZVI/BC fabricated with 0.05 mol/L K2FeO4 (BC-Fe0.05) showed optimal sulfadiazine (SDZ) removal performance in the peroxydisulfate (PDS) activation system with complete removal after 10 min, as it showed the highest adsorptive ability of SDZ. Moreover, BC-Fe0.05 was able to remain stable after four cycles or 80 days of storage. Higher temperature, lower pH, and Cl– were beneficial to SDZ removal efficiency, whereas CO32- and HPO42- had inhibitory effects. Non-radical species (1O2) and radical species (SO4·-, ·OH, and O2·-) both contributed to SDZ degradation, and 1O2 was the most important reactive oxygen species. Four degradation pathways were proposed based on ten identified intermediates. Potential eco-toxicity anal. by ECOSAR suggested that most intermediates were less toxic than their parent compound Overall, this study describes a green fabrication method for ZVI/BC with large SSA using K2FeO4 as the iron precursor. Generally, ZVI/BC with large SSA is an effective catalyst for activating persulfate to degrade antibiotics.
