The invention discloses a carboxylated porous carbon nitrogen oxide nano material, a solid phase microextraction coating fiber prepared from the same and application of the solid phase microextractioncoating fiber to detection of phthalic acid esters. The carboxylated porous carbon nitrogen oxide (HOCN-COOH) nano material is prepared from urea and glucose, and the carboxylated porous carbon nitrogen oxide nano material can not only accelerate mass transfer, but also can provide high affinity to promote enrichment performance. Meanwhile, the obtained carboxylated porous carbon nitrogen oxide nano material is bonded to a stainless steel fiber through a layer-by-layer chemical bonding method to obtain the solid phase microextraction coating fiber which is high in stability, good in reproducibility and long in life, and the solid phase microextraction coating fiber can be used for detection of the phthalic acid esters in marine products, or wines or instant noodles and has good market prospects. 本发明公开了种羧基化多孔氧化碳氮纳
