摘要

研究3-碘-2-丙炔基丁基氨基甲酸酯（3-iodo-2-propynyl butylcarbamate，IPBC）在不同溶液及木材中的紫外光（ultraviolet，UV）降解特性。采用高效液相色谱（high-performance liquid chromatography，HPLC）探讨紫外光波长、辐照强度、溶剂种类、IPBC初始质量浓度和辐照时间对溶液中IPBC紫外光降解性能的影响，以及温度和初始含水率对木材中IPBC紫外光降解性能的影响，最后采用超高效液相色谱-串联质谱法（ultra-high performance liquid chromatography-tandem mass spectrometry，UPLC-MS/MS）鉴定IPBC在正己烷中的紫外光降解产物。结果表明，随着紫外光波长的减小、辐照强度的增加以及辐照时间的延长，IPBC的保留率降低；IPBC在不同溶剂中的紫外光降解速率依次为正己烷＞甲醇＞水；IPBC的紫外光降解符合一阶动力学反应模型（

＞0.99）。升高温度和增加试样初始含水率均可促进IPBC在木材中的紫外光降解。分离鉴定出的8种IPBC在正己烷溶液中的紫外光降解产物，为后续探究处理材在户外应用时IPBC的紫外光降解提供理论依据。

Abstract

The ultraviolet (UV) photolysis characteristics of 3-iodo-2-propynyl butylcarbamate (IPBC) in different solutions and treated wood were studied. High-performance liquid chromatography (HPLC) was used to investigate the effects of UV wavelength

irradiation intensity

solvent type

initial mass concentration of IPBC

and irradiation time on the UV degradation performance of IPBC in solutions

as well as the effects of temperature and initial moisture content on the UV degradation performance of IPBC in treated wood. Finally

ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was used to identify the UV degradation products of IPBC in n-hexane. The results showed that as the wavelength of UV decreases

the irradiation intensity increases and the irradiation time prolongs

the retention rate of IPBC decreases; the order of UV degradation rate of IPBC in different solvents was n-hexane

methanol

water. The UV degradation rate of IPBC in

solution was in accordance with the first-order kinetic model (

＞0.99). Raising the temperature and increasing the initial moisture content of wood promotes the UV degradation of IPBC in wood. Eight types of UV degradation products of IPBC were identified. This study provided a theoretical basis for the UV degradation of the IPBC-treated wood in outdoor applications.
