Optimization of solid-phase microextraction using Taguchi design to quantify trace level polycyclic aromatic hydrocarbons in water.

摘要: This article introduces a simple, rapid, and reliable solid-phase microextraction (SPME) method coupled with GC-MS for the quantitative determination of 16 polycyclic aromatic hydrocarbons in water. In this study, Taguchi experimental design was used to optimize extraction conditions using SPME obtain highly enriched analytes. Consequently, water achieved by technique. The selected parameters affecting enrichment were sample time, stirring speed, temperature, ionic strength, pH. study revealed that optimal operating found be 90-min 1400 rpm 60C temperature. effect strength pH shown insignificant. Optimized also reevaluated placing into several subgroups based on their molecular weight. efficiency low weight function only extractingtemperature.Satisfactoryresultswereobtainedforlinearity(0.983‐0.999),detection limits (2.67‐18.02 ng/L), accuracy (71.2‐99.3%), precision (4.3‐13.5%). optimum reported other approaches evaluated generalized suggested.
