| 中文摘要: |
| 目的 研究不同存储温度对保鲜纸中亚氯酸钠留着率的影响。方法 利用碘量法测定亚氯酸钠的留着率， 用白度仪测定基材白度的变化情况， 用X射线光电子能谱仪 （XPS） 对纤维表面的化学特性进行表征。结果 不同温度下， 亚氯酸钠留着率呈现出不同的下降趋势。通过白度测定结果可知， 木素和亚氯酸钠反应会造成亚氯酸钠留着率降低。XPS测试结果表明， 存储温度升高， 木素和抽出物含量降低。结论 低温环境有利于亚氯酸钠留着率的保持。 |
| 英文摘要: |
| The effects of different storage temperatures on the residual rate of sodium chlorite on preservative papers were studied. By the means of iodimetry, the residual rates of sodium chlorite in the papers were measured. The changes of the whiteness of the papers were measured by whiteness meter, and the chemical properties of the fiber surface were characterized by X-ray photoelectron spectroscopy (XPS). It was found that the residual rates of sodium chlorite showed different decreasing trends at different temperatures. The whiteness measurement results showed that the decreased residual rates of sodium chlorite were caused by the reaction between the lignin and sodium chlorite. The X-ray photoelectron spectroscopy (XPS) test results indicated that the contents of lignin and extractives decreased with the increasing storage temperature. In conclusion, lower temperature was beneficial to maintain the residual rate. |
