尼龙-6改性纤维素纸结合高效液相色谱技术检测水中7种酚类化合物OA

Cellulose paper was utilized as a substrate,and nylon-6 was incorporated into the surface of the cellulose paper through in situ synthesis in formic acid,resulting in a modified cellulose paper.The morphological and structural properties of the modified cellulose paper were meticulously analyzed,alongside the interaction between nylon-6 and cellulose.This modified cellulose paper subsequently served as a solid-phase extraction medium for the enrichment and concentration of seven phenolic compounds present in aquatic systems.A comprehensive experimental methodology for detecting these seven phenolic compounds in aquatic environments via high-performance liquid chromatography(HPLC)utilizing the modified cellulose paper was developed and applied to real samples.The analyses indicated that the recovery rates of the seven phenolic compounds across three types of real samples ranged between 59.0%and 74.7%,with detection limits(LODs)spanning from 0.5 to 4.5 ng/L,and quantification limits(LOQs)ranging from 6.9 to 13.8%.The matrix effect observed was between 96.1%and 104.6%,illustrating that the modified cellulose paper demonstrates significant potential for application in the analysis and detection fields.
