| 中文摘要: |
| 建立了一种利用高效液相色谱仪测定粘合剂RA65中游离甲醛含量的方法。通过对粘合剂RA65进行衍生化前处理后再测试，采用外标法计算得出粘合剂RA65中游离甲醛含量。结果表明，标准曲线的相关因数≥0.995，加标回收率为101.67%～103.33%，游离甲醛含量测定结果的相对标准偏差小于2%。本方法操作简便、快速，结果准确可靠。 |
| 英文摘要: |
| A method was established for the determination of free formaldehyde content in adhesive RA65 by high performance liquid chromatography.The adhesive RA65 samples were tested，after derivatization pretreatment the free formaldehyde content in them was calculated by the external standard method.The results showed that the correlation coefficient of the standard curve was above 0.995，the recovery rates were in the range of 101.67%～103.33%，and the relative standard deviation of free formaldehyde content determination results was less than 2%.This method was simple and rapid to operate，with accurate and reliable results. |
