Bamboo charcoal, a microporous material, was used as a solid-phase extraction sorbent for the enrichment of the three endocrine disrupters: bisphenol A, nonylphenol, and 4-octylphenol from environmental samples. Parameters affecting the extraction efficiency, such as eluant and its volume, flow rate, pH and volume of the sample, were investigated and optimized. The results of HPLC analyses revealed a linear relationship between the peak area and the concentration of the three analytes over the range of 2.0--100\thinspace{\textmu}g L−1, with a precision of 3.0--5.6 % under optimal conditions. The method was applied to the analysis of river water and seawater samples, the recoveries ranged from 79.5 to approx. 104.3 %.
