| 摘要: |
| 采用穿孔萃取法，研究不同影响因素对人造板甲醛释放量检测结果的影响，研究结果表明：碘量法和光度法测得的甲醛释放量差异显著；甲醛释放量随萃取温度的升高而升高；硫代硫酸钠浓度、乙酸铵浓度、乙酰丙酮用量对测定结果影响显著；乙酸铵试剂用量的微小差别对测试结果影响不明显。 |

| Abstract: |
| The factors affecting the determination of formaldehyde released from wood-based panels with extraction method were tested, the results show that: A comparison of formaldehyde emission was made between iodometry method and spectrometer method , significant difference was observed. With the rise of extraction temperature, the formaldehyde emission increase.The effects of concentration changes of reagents (sodium thiosulfate,ammonium acetate) were obviouse,as well as small amount difference of accty-lactone.The effects of small amount difference of ammonium acetate were not obvious. |
| Key words: wood-based panel formaldehyde emission extraction method(perforator method) |
