| 摘 要： | 为了研究漂白条件对烟丝纤维素漂白效果的影响，并定量分析烟丝中纤维素的质量分数，利用Image J色度分析软件，同时结合烟丝纤维素的质量分数和提取率，研究确定了烟丝纤维素漂白的最佳制备工艺。考察了加热温度、加热时间、漂白溶液的pH和漂白次数对漂白效果的影响。结果表明：采用60 mL pH=3的3%（质量百分数）亚氯酸钠漂白溶液，在75℃水浴中加热30 min，重复漂白2次，达到最佳漂白效果，烟丝纤维素漂白提取率为65.32%，质量分数为93.25%，烟丝纤维素压片照片的色度比仅是对照组（Con）的11.67%。利用Image J色度分析软件对烟丝纤维素压片照片的色度比定量分析结果有效。

| Abstract: | In order to investigate the effects of conditions on the bleaching effect of cut tobacco cellulose and quantitatively analyze the mass fraction of cellulose in cut tobacco, Image J colorimetric analysis software was optimized to determine the bleached cut tobacco cellulose based on its mass fraction and extraction yields. The influences of heating temperature, heating time, pH of bleaching solutions, and bleaching times on bleaching effects were investigated. The results showed that the best bleaching effect was achieved by using 60 mL of 3% sodium chlorite bleaching solution at pH 3 and heating in a water bath at 75 ℃ for 30 min and two times. The yield and mass fraction of cellulose after being bleached were 65.32% and 93.25%, respectively. The chromaticity ratio of the cellulose tablet photo was only 11.67% of that of the control group. In conclusion, Image J colorimetric analysis was effective for the quantitative analysis of chrominance ratio of cut tobacco cellulose. |
