Multi-walled carbon nanotubes (MWCNs) are used as adsorbent for solid-phase extraction (SPE) of several chlorophenols (CPs). CPs were adsorbed on MWCNs cartridge, then desorbed with pH 10.0 methanol, finally determined by HPLC. Under the optimized conditions, detection limits of 0.08-0.8 ng mL(-1) were obtained. The method had been applied to analyze the five CPs in tap water and river water.
多壁碳纳米管（MWCNs）被用作几种氯酚（CPs）固相萃取（SPE）的吸附剂。氯酚被吸附在多壁碳纳米管柱上，然后用pH值为10.0的甲醇解吸，最后通过高效液相色谱法进行测定。在优化条件下，检测限为0.08 - 0.8 ng mL⁻¹。该方法已应用于分析自来水和河水中的五种氯酚。
