Micro-solid phase extraction methods based on molecularly imprinted polymer for determination of toluene metabolites in urine samples
Toluene is one of the most widely used solvents in various industries. Workers exposure to toluene can be monitored using hippuric acid and o-cresol as urine biomarkers for biological exposure index. However, extraction of biological fluids often results in sample emulsification in liquid-liquid ext...
