摘要：

A solid phase extraction (SPE) method was developed for phenol, 4-nitrophenol, 4-chlorophenol and 4-cyanophenol from the wastewater. The recoveries were 95%, 93%, 92% and 90% for phenol, 4-nitrophenol, 4-chlorophenol and 4-cyanophenol, respectively. The elution was carried out by methanol (1 mL) at 0.25 mL/min. flow rate. The optimisation of SPE was achieved by using different eluting solvents, pH of wastewater, flow rates and other factors. Validation of the developed methodology was carried out using Microsoft Excel program. Possible mechanisms were presented for SPE of phenols.
