| 摘 要： | 建立了反相高效液相色谱法（HPLC）测定酚醛胶人造板中游离苯酚含量的方法。本文采用C18柱（250×4．6mm，5μm）对酚醛胶人造板中的游离苯酚进行了HPLC检测，比较了不同流动相配比和不同流速条件下的苯酚的出峰情况。结果表明，在流动相为65％甲醇＋35％水，流速0．8mL／min，UV检测波长为254nm的条件下苯酚的出峰时间和分离效果最好，检测限为0．5μg／mL，相关系数r=0．9994，相对标准偏差为0．87％（n=5）。实验结果表明该方法可行，快速简便，准确可靠。

| Abstract: | A HPLC method for determination of free phenol was established. RP--HPLC was applied for quantitative analysis free phenol. Diamonsil RP-- C18Colmnn（250 mm ×4.6 mm,5μm）is used and a mixture of methanol--water（65：35 ）as the mobile phase ,flow rate was 0.8 mL/min, column temperature was room temperature,UV detected at 254nm. The limit of detection was 0. 5μg/mLo RSD was 0.87 % （n =5） and the correlation coefficient （r） is 0. 9994 o The results show that the method is feasible, rapid, simple and accurate. |
